Given:
Car 1 started from home at miles per hour.
hours later car 2 started from home to catch car 1.
After car 2 traveled hours,it was still miles behind car 1.
Find the velocity of car 2. (Remember to enter your units)

Velocity v2 =


Example:

In the morning the passenger train left the station going 7 miles per hour
At the same time the freight train left the station going 3 miles per hour.
Find the time it takes for the passenger train to go 10 miles farther than the freight train.

In shorthand form the problem can be written as follows:
Passenger train distance dp = vpt = vft + 10.
