Question

Two boats start together and race across a 46 km wide lake and back. Boat A goes across at46 km/h and returns at 46 km/h. Boat B goes across at 23 km/h, and its crew, realizing how far behind itis getting, returns at 69 km/h.Turnaround times are negligible, and the boat that completes theround-trip first wins. (a) Which boat wins? (Or is it a tie?) 1 boat A
boat B
it's a tie

By how much?
2 km

(b) What is the average velocity of the winning boat?
3 km/h (a) Which boat wins? (Or is it a tie?) 1 boat A

(b) What is the average velocity of the winning boat?

Explanation / Answer

boat A wins because by the time boat B make the upwardjourney in 2 hours @23 kmph the boat A completes the journey. boat A wins the game by 46 km the average velocity of the winjning boat is zero.because itreaches the initial point .so the displacement is zero.so theaverage velocity is zero.
