Question

Two boats start together and race across a 44 km wide lake and back. Boat A goes across at 44 km/h and returns at 44 km/h. Boat B goes across at 22 km/h, and its crew, realizing how far behind it is getting, returns at 66 km/h. Turnaround times are negligible, and the boat that completes the round-trip first wins.
Which boat wins and by how much? (Or is it a tie?)
(a) By how much? (Enter NONE if it was a tie.)
km
(b) What is the average velocity of the winning boat? (Enter NONE if it was a tie.)
km/h .... I put 44 for this answer and it was.

Answer 1

Answer:

a. 44 km

b. 0 km/h

Explanation:

For part a, the faster boat finishes when the second turns around to come back.

For part b, the average velocity is zero because he travels forward (+) and then back (-). 44km/h - 44 km/h = 0 km/h
