<em>Answer: </em>

<em>Elena's running speed is 5 miles/hour </em>

<em>Explanation: </em>

<em>The speed is defined as the covered distance per unit time </em>

<em>In the problem, we have: </em>

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

<em>We are also given that she completes each lap (she completes  of a mile) in  of an hour </em>

<em> </em>

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

<em>This is done as follows: </em>

<em>speed =  miles/hour </em>

<em>This means that: </em>

<em>Elena can run 5 miles each hour</em>
