Problem: A swimmer swims in a river where the current is 0.57 m/s east. The swimmer swims west for 300 m and then east for 300 m. The swimmer's speed with respect to the water is 1.2 m/s.

Part B: How much time does it take to swim 300 m downstream?
Please show your work, so I can understand process. Thanks!
