Question

A girl leaves school for a cycle ride and comes back school after an half-an-hour ride covering a distance of one km. What is the average velocity of the ride? *

Answer 1

Answer:

0

Explanation:

coz displacement = 0

Answer 2

Answer:

As the girl started from the point and came back to the same point, the displacement = 0

time = 1/2 h

we know that

$average \: velocity = \frac{total \: displacement}{total \: time}$

$= \frac{0}{ \frac{1}{2} }$

$= 0$

There fore ,the average velocity of the girl = 0
