Question 900989: I think I have the right answer but I am not sure.
A truck enters the highway going 60 miles per hour. Ten minutes later, a car enters the highway going 70 miles per hour. How long, in minutes, does it take for the car to pass the truck?
Truck:
d=60x+10
r=60
t=x
Car:
d=70x
r=70
70x=60x+10
70x-60x=10
10x=10
x=10/10(60)
x=60 minutes

The truck goes 60*10/60=10 miles in ten minutes before the car pursued it.
The car is gaining on the truck at 10 mph so it will take one hour to gain 10 miles
