Suppose you are standing in a field near a straight section of railroad tracks just as locomotive of a train passes the point nearest to you, which is 1/4 mile a way.
The train, with length 1/3 mile, is traveling at 20 mph.
If you start running a straight line across the field, how slowly you run and still catch the train?
In which direction you should run?
Run directly to the nearest point of the tracks
Find how long it takes the end of the train to get to this point. t = dist/speed
t = %281%2F3%29%2F20 = .0617 hrs
Find how fast you have to run to travel 1/4 mi in .0167 hrs. s = dist/time
s = %281%2F4%29%2F.0167
s = 1.33 mph to arrive just as the last car is at that point
