A father and son used to go outside together when it was windy to fly their kite. One day the father calculated that he had allowed 140 m of rope to climb. The father also noted that his son was directly under the kite (in order to see better) and standing 50 m from him. How many yards is the kite from the ground (assuming the rope is tight)? *
