First, we'll have to write two linear equations for the two cars. I’m denoting the front car as Car 1 and the second car as Car 2. For distance traveled, ”d” will be our variable. For hours, ”h” is our variable.
Car 1 Equation: d = 60h Car 2 Equation: d = 70h
Messing around with the ”h” variable, we get 6 hours
So in 6 hours, Car 2 will be in front of Car 1 by 10 miles.
Little hint: Every hour, Car 2 gets closer to Car 1 by 10 miles
