On a pleasure cruise a boat is traveling relative to the water at a speed of 4.94 m/s due south. Relative to the boat, a passenger walks toward the back of the boat at a speed of 1.80 m/s.
(a) What is the magnitude of the passenger's velocity relative to the water?
(b) How long does it take for the passenger to walk a distance of 36.7 m on the boat?
(c) How long does it take for the passenger to cover a distance of 36.7 m on the water?
