## Camping TripMath brain teasers require computations to solve.Gretchen and Henry decide to go camping on a river. From where they put their canoes in the water, they paddle upstream for 3 hours, only to realize that their campground is located downstream from their starting point. They immediately turn around, and paddle downstream for the next 5 hours.
That night, they get some rest, make some s'mores, and tell ghost stories. They wake up the next morning to get back on the river, and paddle back to their starting point, 26 miles upriver. Henry, knowing that this river flows at a constant rate of 2 miles per hour, says, "There's no way we're getting back by nightfall." Gretchen does some quick math with a stick in the dirt, and says, "If we paddle at the same constant rate we did yesterday, we'll be back in time for a 6:00 dinner." What time are they leaving? ## What Next?
