Each day a man floating on a raft paddles 3 mi north, but each night while he rests, the current of the river carries the raft 2 mi south. How many days will it take him to first reach a location 50 mi north of his starting location?

A day the man floats \(3-2=1\) (mi north)

So until 47 days the man can go 47 mis north ( Cause 1 mi / day).

In the last day (day 48) the man floats 3 mi north so the distance he went is 47 + 3 = 50 (mi north).

So it will take him 48 days to reach the location.
