A river flows at an average speed of 2 m/s. A boat travels upstream a distance of 500
meters and then returns to its starting point.
(a) What is the boat’s average speed relative to the river bank (in m/s) if the round trip
takes 15 minutes?
(b) What is the boat’s average velocity for the entire trip (in m/s)?
(c) What is the boat’s average speed relative to the water (in m/s) if the round trip
takes 15 minutes? The boats speed with respect to the water is constant.
