Piece of Cake

The Dunn Middle School Piece of Cake bike ride this weekend is a slow ride up the big hill along Santa Rosa Creek from Cambria, followed by a fast downhill to Morro Bay. I don't know the actual distances up and down, but they're close, so we can assume they're equal for this stumper. It's steep, so you pedal (and push) up the hill at an average speed of just 5 miles per hour. Then you zoom down to the end as fast as you can. How fast do you have to ride down so that your average speed for the whole trip is 10 miles per hour? Careful, this is a stumper!
