Question

Please help me out with this related rates Problem:

A child is flying a kite. If the kite is 90 feet above the child's hand level and the wind is blowing it on a horizonatal course at 5 feet per second, how fast is the child paying out cord when 150 feet of cord is out? (assume that the cord remains straight from hand to kite, actually an unrealistic assumption.)
