A train travels due north at 40 mph. A car travels toward the train from the same starting point leaving 2 hours later than the train. If the car is traveling at 60 mph, how many miles will the car have to travel to catch up to the train?
Accepted Solution
A:
train: (h+2)*40 car: h*60
when does the car catch up to the train? train=car (h+2)*40=h*60 40h+80=60h 80=20h 4=h
How many miles did the car drive after h=4 hours/when it catches the train? 4*60=240 miles
