Solution

The correct option is B $0$
Net displacement during this activity $= 0$

Average velocity= $\frac{Total Displacement}{Total time}$ ,

Here athlete returns to the starting point so displacement is zero.

Average velocity= $\frac{Total Displacement}{Total time}$ = $\frac{0}{42} = 0$ $m / s$ .
Option D.

Q. In planning for a car trip, Joan estimated both the distance of the trip, in miles, and her average speed, in miles per hour. She accurately divided her estimated distance by her estimated average speed to obtain an estimate for the time, in hours, that the trip would take. Was her estimate within 0.5 hour of the actual time that the trip took?
(1) Joan's estimate for the distance was within 5 miles of the actual distance.
(2) Joan's estimate for her average speed was within 10 miles per hour of her actual average speed.
