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)? This is a hard one...If you turn in correct work for part C, you will receive 10 EC points on the exam!!! (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. Answer Box: a = 1.11 m/s b = 0.00 m/s c = 2.63 m/s 3
