please dont give me a wrong awnser plz ​

Answer 1

Answer:

her average velocity was 100 kilometers per hour south.

Explanation:

The average velocity of an object is its total displacement divided by the total time taken. In other words, it is the rate at which an object changes its position from one place to another. Average velocity is a vector quantity(Byjus).

Hence, the formula for average velocity is;

$v = \frac{Total Displacemet}{Total time taken}$

This is not the same as the instantaneous velocity obtained at each point along the journey.
