A boat crossing a 254.0 m wide river is directed so that it will cross the river and land on the opposite shore directly across from the starting point. The boat has a speed of 6.20 m/s in still water and the river flows uniformly at 3.10 m/s. Calculate the time required for the boat to reach the opposite shore.
