Two swimmers simultaneously jumped off a raft floating down a river and swam in opposite directions: the first - downstream, and the second - upstream. After five minutes, they turned around and soon returned to the raft. Who returned first? (Each swimmer maintains a constant own speed.)

#
From the point of view of a person on a raft, each swimmer always swims at their own speed.

## Solution

Relative to the raft, each swimmer always swims at their own speed (regardless of whether they are swimming with or against the current). According to the problem, each swimmer swam for 5 minutes, moving away from the raft. Therefore, it will take them another 5 minutes to return.

## Answer

The swimmers returned simultaneously.
