I have a problem in my D.E. class that is driving me nuts. Two drivers, A and B are in a race. Beginning from a standing start they both proceed at a constant acceleration. Driver A covers the last 1/4 of the distance in 3 seconds. Driver B covers the last 1/3 of the distance in 4 seconds. Who wins and by how much time? I am assuming the distance is 1320ft or 1/4 mile. I know that driver B wins by .594 seconds but I don't know how that number was reached. Can anyone help?
