Question 648824: Travel by car: Marcus drives from one town to another in 6 hours. On the return trip, his speed increased by 10 mph and the trip takes 5 hours. Find his rate on the return trip. How far apart are the towns?
So far I know:
rate x time= distance
Going trip- rate= r time =6 distance= ?
Return trip- rate= r+10 time= 5 distance=?
I am not sure how to proceed in writing and solving the equation.
