Answer 2

Answer:

Elena's running speed is 5 miles/hour

Explanation:

The speed is defined as the covered distance per unit time.

In Problem we have:

The distance covered is the length (circumference) of the circular track which is given as 1/4 of a mile.

We are also given that she completes each lap (she completes 1/4 of a mile) in 1/20 of an hour

To get her speed, we will divide the distance covered by the time taken to cover this distance

This is done as follows:

Speed= 1/4 / 1/20

= 5 m/h

This means that:

Elena can run 5 miles each hour

Hope this helps you :)
