Two piers A and B are located on a river; B is 1500 m downstream from A. Two men must make round trips from pier A to B and return. One man is to row a boat at a constant speed of 1.11 m/s relative to the water, and the other man is to walk on the shore at a constant speed of 1.11 m/s. The velocity of the river is 0.78 m/s in the direction from A to B. How Much Time does it take each person to make a round trip?
