In the classic book by Jules Verne,Phileas Fogg travels around the world in 80 days.Leaving London,heading east,and arriving back in London 80 days later from the west.If the radius of the Earth is 6.38 x 10⁶ m (for this problem,treat London as being on the equator),find the average velocity of Mr.Fogg.

Question

Quizplus · Accepted Answer

The average velocity of Mr. Fogg is zero because velocity is a vector quantity, which means it takes into account both magnitude and direction. Since Mr. Fogg starts and ends his journey in the same location (London), his displacement is zero. Since average velocity is displacement divided by time, and his displacement is zero, his average velocity is also zero, regardless of the path taken or the distance traveled.
