Question

Canoe and River Current Timing

Context

Two friends paddle on a river with a constant current of 2 mph. Their paddling speed relative to the water is constant and the same on both days.

Day 1: Starting at their original launch point, they canoe upstream for 4 hours, then immediately turn and paddle downstream for 5 hours.
Day 2: From where they ended Day 1, they paddle upstream back to the original launch point, which is 23 miles upstream from their Day 2 starting location. They arrive at 16:00.

Task

At what time did they depart on the return trip (i.e., the Day 2 upstream trip back to the original launch point)?
