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
