Problem: Harry is on a boat that is capable of a maximum speed of 10 kilometers per hour in water, and wishes to cross a river 2 kilometer wide to a point directly across from their starting point.
Part A: If the speed of the water in the river is 5 kilometers per hour, how much time is required for the crossing?
I need help to determine how much time is required for the crossing.
