My god, I hope noone I know is reading this board, it's embarrassing..
If a car is going at 25 miles an hour over a distance, then that is the same as if it was going half the time at 0, and half the time at 50.
Right ?
So that is that same as if it was going FROM 0 to 25 (at the mid-point - this being our constant linear acceleration assumption), THEN from 25 to 50 to 'make up' for the slower 1st half.
The graph is a straight line from 0 to 50. This is the same area as if it were a straight line across from starting at 25, and ending at 25.
SO, the time is the time taken to go 600 feet at 25 miles per hour.
