<PRE><B>Question 897622</B>
A truck enters a highway driving 60 mph. A car enters the highway at the same place 10 minutes later and drives 65 mph in the same direction. From the time the car enters the highway, how long will it take the car to pass the truck?
***
let x=time it takes for car to pass truck.
distance=speed*travel time
10 min=1/6 hr
60(x+(1/6))=65x
60x+10=65x
5x=10
x=2
how long will it take the car to pass the truck? 2 hrs</PRE>
