Question 334273: While traveling at 65 mph, a car passes a train from back to front in 2 minutes. At the same time, another car, also traveling at 65 mph, moves from the front to the back of the train in 10 seconds. If the train travels at a constant speed, how long is the train?
I found the distance it took each car to pass the train in the given times using d=rt. The car moving from back to front takes 2 minutes, and therefore 2.1667 mi. The car moving from front to back takes 10 seconds, and therefore 0.1806 mi.
