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?
I don't understand why it has to be converted to 10/60. Cause it is already in miles per hour. You said that it has to be converted because it is in kilometers per hour but the question definitely says miles per hour.
