If it accelerated linearly, then we can say that it took twice the time that it would have taken were it travelling at its fully speed...
So, 600feet at 50mph = 50/60(5280)/60seconds = 73.33 feet per second, so 600/73.33 = 8.1821901 seconds, * 2 =
16.3643802 seconds.
This assumes it accelerates in a perfectly linear fashion.
It is simply the area under the time distance graph, which - because it starts at 0 and ends at 50mph, is simply a traingle with half the area of the time/distance graph were it at 50mph the whole time.
