Atruck enters a highway driving 60 mph. a car enters the highway at the same place 5 minutes later and drives 74 mph in the same direction. from the time the car enters the highway, how long will it take the car to pass the truck?

Recall your d = rt, distance = rate * time.

let's say by the time the car gets in the highway, the truck has already been running for 5 minutes, and say by the time they meet the truck has been running for "t" hours, so the car has then been runnning for 5 minutes less than "t", now, since "t" is hours well, 5 minutes is just 5/60 or 1/12 of "t", so the car has been running when they meet for "t - 1/2"

now, just before the car passes the truck, they first have to meet, at that point, the distance travelled by both is exactly the same, say "d" miles.



which is about 26 minutes and 25 seconds.

Add the cents that add the left overs to get the first number
