Question 830501: When you kayak on a river, you can paddle 15 mph in still water. The river is running at 10 mph downstream. You paddle for an hour, going upstream and stop. If you allow the current to carry you downstream, how long will it take?

You can put this solution on YOUR website!
Your speed upstream is 15-10=5 mph.

Your paddling travel, 5%2A1=5 miles.

Now you let the river current carry you the 5 miles back at its 10 mph.
10%2Ah=5
h=5%2F10
h=%281%2F2%29, half hour
