Homework Help: physics

Posted by Jean on Wednesday, September 3, 2014 at 10:49pm.

A child, who is 45 m from the bank of a river is being carried downstream by the river's swift current of 1.0 m/s. As the child passes a lifeguard on the river's bank, the lifeguard starts swimming in a straight line until she reaches the child at a point downstream. If the lifeguard can swim 2.0 m/s relative to the water, how long does it take her to reach the child? How far downstream does the lifeguard intercept the child?
