You commute 56 miles one way to work. The trip to work takes 10 minutes longer than the trip home. Your average speed on the trip home is 8 miles per hour faster. What is your average speed on the trip home?

Answer 1

Consider going to home:

56=vt
going to work:
56=(v-8)(t+10/60)

now solve. If you get stuck, repost. You have two equations, two unknowns.
