1. The problem statement, all variables and given/known data A lifeguard who can swim at 1.2 m/s in still water wants to reach a dock positioned perpendicularly directly across a 550 m wide river. a. If the current in the river is 0.80 m/s, how long will it take the lifeguard to reach the dock? b.If instead she had decided to swim in such a way that will allow her to cross the river in a minimum amount of time, where would she land relative to the dock? (10 marks) 2. Relevant equations 3. The attempt at a solution I already figured out a with the Pythagorean theorem and so his avg speed is 1.44 m/s and then t= d/Vavg to give me 347,22 sec and so it will take him 345.22 seconds to reach the dock. but my question is for b. It has me stumped.
