Answer:
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

1. The equations are Consistent and Independent because they intersect at only one point.
2. The equations are Consistent and dependent because there are infinite solutions.
3. The equations are Inconsistent because they never intersect.
4. The equations are Consistent and Independent because they intersect at only one point.
I hope this helps :)
