Question

A circular running track is 1/4 miles long Jane runs on this track completing each lap in 1/20 of an hour what is James running speed

Answer 1

James running speed is 5 Miles per hours

Explanation:

Given:

Length of the circular running track = 1/4 miles

Time Taken for Jane to make one complete lap = 1/20 of an hour

To Find:

James running speed = ?

Solution:

Let the speed at which James is running be X

then , we know that

`Speed = (Distance)/(Time)`

`Speed = ( (1)/(4) )/( (1)/(20) )`

`Speed = (1)/(4) } *(20)/(1)`

`Speed = (20)/(4)`

Speed = 5 Miles per hours
