A boat moves at 10.00 m/s relative to the water. If the boat is in a river where the current is 2.00 m/s, how long does it take the boat to make a complete round trip of 1000.0 m upstream followed by 1000.0 m downstream?

First Answer
Time for upstream =1000/(10-2) =125sec
Time for down stream =1000/(10+2) =83.33 sec
Total time = 208.33 seconds.
Time for down stream =1000/(10+2) =83.33 sec
Total time = 208.33 seconds.
