Question

Ann walked 1.5 miles south to her house in 0.5 hours. what is Ann's speed? what is Ann's velocity

Answer 1

To calculate the speed and velocity of the Ann`s we use the formula,

`v= (d)/(t)`

Here, d is distance and t is time and v if we take it with direction then it is called velocity and if we take it without the direction then it is called speed.

Given
`d=1.5 miles` and
`t=0.5 hours`.

Substituting these values in above equation we get

`v=(1.5mi )/(0.5 h) = 3 mi/h`

As Ann walked towards south direction therefore, Ann`s velocity is 3 mi/h south and her speed is 3 mi/h .
