Question Two cars are driving around a two-mile track. One car makes a lap every
eighty seconds. The other car makes a lap every sixty seconds. At these rates,
how long will it take the faster car to gain a lap on the slower car?
For this problem I subtracted 80-60=20 seconds to find the difference
between the two drivers. Then I divided 60/20=3 to find out how many 20
second intervals are added onto the slower driver's time every lap. I don't
know if I worded that correctly. Lastly, I multiplied the faster driver's time by
how many laps that need to be run in order to lapse the slower driver
(80x3=240 seconds). Could you tell me if I solved this question correctly and
if so did my explanation make sense?
