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

All you have to do is swich the numbers
Test them
(x,y)
(2,4) and (3,3)
see if get true
(2,4)
-3(2)+5(4)=2(2)+3(4)
-6+20=4+12
14=16
false
(3,3)
-3(3)+5(3)=2(3)+3(3)
-9+15=6+9
6=15
false
neither
