Problem: A child in danger of drowning in a river is being carried down-stream by a current that flows uniformly with a speed of 2.20 m/s . The child is 400 m from the shore and 2100 m upstream of the boat dock from which the rescue team sets out.If their boat speed is 8.00 m/s with respect to the water, at what angle from the shore must the boat travel in order to reach the child?
