Question

A girl swim in swimming pool of length 100m she swims from one end to another and reaches the starting point again 2 minutes what will be the average velocity of summed

Answer 1

Answer:

0

Explanation:

Displacement is can be said to be the minimum distance between starting and end points.

In this question, the girl swims and then comes back to her original position. As a result, her displacement becomes 0, because her start and end points are same, ie minimum distance is 0.

Now,

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

here total displacement is 0 m

Hence, avg velocity becomes 0m/s.

ANSWER:

Avg velocity = 0 m/s.

I hope that u understand that this tricky question.
