Two cars leave town going in opposite directions. The car heading north travels at 55 mph. The car heading south travels at 75 mph. How long will it take them to get 715 miles apart?



4+4=


What??

distanceapart=(55 + 75)*time
solve for time.

So the equation is:
715=(55+75)t



715=(55+75)t

55+75=130
the answer should be
t= 5.5
Try it on your calculator i don't want to get it wrong for you :)
