Question

2 cars are driving around a 2 mile track. 1car makes a lap every 80 seconds, and the other every 60 seconds. At these rates, how long will it take the faster car to gain exactly 1 lap on the slower car?

show work, tell how you did it.

Answer 1

Car 1 is traveling at 2mi/80sec = 1mi/40sec = Rate1

Car 2 is traveling at 2mi/60sec = 1mi/30sec = Rate2

Time = Total Distance / Rate

T = X1 / Rate1

T = X2 / Rate2

For this problem we want to know when Car 2 is 2 miles ahead of Car 1, so:

X1 + 2 = X2

X1 / Rate1 = X2 / Rate2

X1 / Rate1 = (X1 + 2) / Rate2

Solve for X1, then find T.

You should be able to figure it out from here.

Answer 3

You want me to do your homework. I will decline. This question doesn't belong under cars/safety by any stretch of the imagination.

Thumbs down for not helping you cheat? And you can't even ask in the right place? idiot.
