a man rows his boat up a river at a constant speed when opposite a cabin on the shore, he drops a bottle in the water,
he continues rowing upstream for 15 minutes then he turns around and rows downstream until he catches up with the bottle, at which point he is 1 mile downstream from the cabin
how fast is the river flowing?
:
Since they are both in the water, the current has no affect on their relationship
If he rowed 15 min away from the bottle, it would take him 15 min to return to it
The round trip would be 1/2 hr
During this half hour the current carried the bottle 1 mi, therefore
rate of the current = 2 mph
