if you give a shit about math, which I don't, but i've a math problem I thought up when I saw a jet pass by and yeah, here's the jist of what needs figuring out:
20seconds = 3600seconds
500ft = x miles

@479,739 (A)
I think you mean 1 miles per 20 seconds -> 0.05 miles/sec
but then how does that related to 500ft = x miles
the 2 equations does not compliment each other

He must be retarded.

Is he really asking ...If it takes 20 seconds to travel 500 feet how fast are you going.

Hopefully he will put pen to paper and do his own fucking homework.

In life it is more important to understand the process for finding a solution. The final correct answer is not as important.
By the way. (500 feet) / (20 seconds) =
7.62 m / s
Show us step by step how you arrived at 340.

OP do this,
By the way Einstein did this and its called a mind problem.
Think about 500 feet. You want to get there in 20 seconds.
You probably already know that fast cars can do a mile in 6 seconds and you have an idea how fast they are going.
So 20 seconds is a great deal of time and 500 feet is a small distance. Its best when you are struggling to solve a problem to break it down to basics.

Consider this. You get on a bicycle. 500 feet of travel and you have 20 seconds to get there.
Don't you think 340 MPH is a bit much?
Now actually if one were to make this a Calculus problem. Its possible in theory to travel at 340MPH for a segment and slow down at end or put a segment anywhere in the travel zone or go very slow 90% of the way and then jump to something larger then 340.
Bottom line is 340 MPH is just not the answer. Its something you can do on a bike.

Nice dream. The answer must include - Jet crashes. It simply cannot go that slow.
Change the 20 to 2 seconds and a jet can go that slow on take off or at landing.

No its not.
I pointed out the problem could require a Calculus solution - I left out what Triptch pointed out - Altitude
Any increasing altitude adds Trigonometry into the Equation. The problem is no longer a straight line point to point - It becomes a Parabola and requires Trig.
But in OP's case no Trig is required because OP States he is between both the buildings - And
(500 feet) / (20 seconds) = 7.62 m / s
A vary slow rate of speed.
Syntax might point out a case could be made for something other than an aircraft. Satellite or Meteor-Comet. Trig would in this case for items in space at say 1500 miles altitude - Speed would be in the order of 17,500 MPH and if OP were to stand at the edge of one of the buildings it could take 20 seconds to pass over from one building to the other.
As OP states the problem - He best get out of the way of the stalled aircraft because he going to get squashed.

Speed = Distance / Time
340 MPH = 498.7 Feet per second.
Got that simple algebra. In just one second at 340 MPH the travel is rounded off = 500 Feet.
You now have 19 seconds left over to contemplate. Have you considered laying out a course on the street. With watch in hand run 500 feet and do this in 20 seconds. Unless you're an crippled? You can do the 500 Feet in 20 seconds without breaking a sweat.

Out of curiosity I looked up how fast can a fly fly in MPH.
A fly can easily do your 500 feet in less then 20 seconds. A bee would take a little longer.
Hint. You need to get off the internet and give the 500 foot course a test with a watch. Or catch a fly and place some ground round at the end of the course and let go of the fly and time it.

Einstein say yes. Meteorologist might suggest yes no or maybe. After all a tail wind might prove the fly will take a few seconds longer then without the tail wind. A bird could catch that fly and totally fuck up the experiment.

here's my cheat sheet. maybe whatever you seek is in here somewhere.
> Straight lines as in completely vertical or completely horizontal are either y=some number or x=some number. Any horizontal line is of the y=some number variety and any vertical line is of the x=some number variety. This can be derived from the slope intercept form of graphing, which is y=mx+b. The "m" is generally the slope of the line and the "b" is where the line will cross the y-axis.

B will be where the line crosses the y-axis and m can be determined using the point-slope formula {(y-y1)/(x-x1) x cannot equal zero}. To use the point-slope pick two numbers where the line crosses the y-axis, subtract them and divide them by the difference of two numbers where the line crosses the x-axis.

here's my cheat sheet. maybe whatever you seek is in here somewhere.

and do you know what a true lazy fuck will do?
open google.com, type "500 feets per 20 seconds = ? miles per hour", hit search, ???, PROFIT!
so, definitely unintelligent.

indeed
why do your own calculation when there's an army of yellow monkies waiting to do it for you?
you just need to be intelligent enough to type it into google (spoiler: that's not very intelligent demanding)

I dunno. I used my knowledge of svg to make a graph to simplify things: http://vectorfag.lostsig.co/view_graph.htm
Unfortunately, it only works as a local file that you edit, because I don't know fuck about javascript. But then, javascript probably wouldn't use svg for the graph at all, which would be gay.
Also this particular version was made for distribution to my classmates, which never happened, but that's why I bothered to comment the svg and add a reload button and instructions to the web page.

It's basically just counting pixels and simple math. The syntax itself is fairly simple. ...Unless you're making arcs. Arcs fucking suck.
I first hand-coded an svg in 2011. Guess what it was.

Oh boy and super useful for vector calculus.
Trick on doing partial derivatives learning wise and later if you need to use it - be very very careful and go S L O W
Multi-dimensional math when done on flat paper - it is difficult and its easy to lose track of a variable or two when you have many to deal with - List each variable before you start and check off each step of the way to be sure you do not drop one of them and end up with a final solution that may be somewhat accurate but will cost you a grade.
There are multiple appls that will do the calculations for you up to some point depending on number of variables - Best to use them only AFTER you do everything by self step by step and really when you do this stuff one step at a time is no different then basic algebra - Just looks intimidating.
Odd how my Dyslexia never gets in the way UNLESS someone hands me their unfinished problem and expects me to find the error - I cannot - I have to start from scratch and do it step by step
Others I no can jump in the middle and find the error
