Cars are moving in the same direction, one at 40mph, the other at 120mph. They are 160 miles apart when the clock starts. The fast car is behind. When will they be next to each other?
***
let x=distance slower car traveled
x+160=distance faster car traveled
travel time=distance/speed (same for both cars)

120x=40(x+160
120x=40x+6400
80x=6400
x=80
x+160=240
x/40=240/120=2
When will they be next to each other? In 2 hours
