Thomas and Ashley are swimming in a river which is 15 m wide. Both swim with a speed u = 1.2 m/s relative to the water, which is flowing downstream at a speed v = 0.25 m/s. They both leave a point on one bank at the same time. Thomas swims directly upstream a distance 15 m, then turns back and swims downstream to his starting point. Ashley points herself so that, taking account of the current, she can swim to a point directly across the river and then turns around and swims directly back to their starting point. How much time does each take to make their 30 m round trips?
Note: do the problem non-relativistically

A swimmer, capable of swimming at a speed of 1.80 m/s in still water (i.e., the swimmer can swim with a speed of 1.80 m/s relative to the water), starts to swim directly across a 1.70-km-wide river. However, the current is 1.18 m/s, and it carries the swimmer downstream. (a) How long does it take the swimmer to cross the river? (b) How far downstream will the swimmer be upon reaching the other side of the river?

Brandon is on one side of a river that is 80 m wide and wants to reach a point 300 m downstream on the opposite side as quickly as possible by swimming diagonally across the river and then running the rest of the way. Find the minimum amount of time if Brandon can swim at 2 m/s and run at 6 m/s. (Use decimal notation. Give your answer to two decimal places.) The minimum amount of time is

Bill and Jill both average swimming speeds of 3.0 m/s, in a pool (that has no current). Bill and Jill go down to the river for a swim, the river has a current of 1.0 m/s straight EAST and is 1.50 x 102 m in width. They are standing on the SOUTH shore. a.Bill, not thinking about the current, jumps in and swims straight across to the North shore. Of course the current affects his resultant velocity and he doesn’t...

A 370 -m-wide river has a uniform flow speed of 1.1 m/s through a jungle and toward the east. An explorer wishes to leave a small clearing on the south bank and cross the river in a powerboat that moves at a constant speed of 7.6 m/s with respect to the water. There is a clearing on the north bank 18 m upstream from a point directly opposite the clearing on the south bank. (a) At what angle, measured relative...
