Answer 1

Elena's running speed is 5 miles/hour

Explanation:

The speed is defined as the covered distance per unit time

In the problem, we have:

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

We are also given that she completes each lap (she completes of a mile) in 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 = miles/hour

This means that:

Elena can run 5 miles each hour
