The sister’s average velocity is mathematically given as

v= 2 m/s.  Option B.

What is her sister’s average velocity?

When an item is moving, its velocity is the rate at which its direction is changing as seen from a certain point of view and as measured by a specific unit of time.

Generally, the equation for the average velocity is  mathematically given as

v = d2-d1/t

Therefore

v = (15-5)/5

v= 2 m/s.

In conclusion, the average velocity is 2 m/s.
