**Ms. Sue**, Wednesday, March 9, 2011 at 12:48pmYes, you're right -- and you're welcome.

I'm not a math teacher and I often am confused about how to solve a problem. However, I usually can estimate the answer. For instance if the trail were 5 km long, then obviously their average speed is 1 km per hour. So your answer of 1.5 km per hour for a longer trail must be right.
