Ann walked 1.5 miles south to her house in 0.5 hours. what is Ann's speed? what is Ann's velocity
ipn [44]

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

v= \frac{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=\frac{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 .
