Question

Julie ran 8 laps around the school’s quarter mile track in 18 minutes.Her average velocity was__m/s.

Answer 1

We have the next information

d=8 laps

t=18 min

v=?

First we need to have the total distance in meters

1 laps = 1/4 mile

8 laps =2 miles

1 mile =1609.34 m

2 miles =3218.69m

d=3218.69m

then we need to transform

1min=60seg

18 min- 1080 seg

Then we have the formula to calculate the velocity

$v=\frac{d}{t}$

we substitute the variables

$v=\frac{3218.69}{1080}=2.98\text{ m/s}$
