Ennis ran 3 miles in 20 minutes and continues running at this rate for 1 hour. Cindy ran 6 miles in 30 minutes and continues running at this rate for 1 hour.

Step-by-step explanation:

Step one:

given data

For Ennis

distance covered= 3 miles

time taken = 20 minutes

Hence Ennis speed is

velocity= distance/time

velocity= 3/20

velocity=0.15miles per minutes

Therefore in 1 hour that is 60 minutes the distance she will cover is

distance= velocity * time

Distance= 0.15*60

Distance= 9 miles

Step two:

For Cindy

distance covered= 6 miles

time taken = 30 minutes

Hence Cindy speed is

velocity= distance/time

velocity= 6/30

velocity=0.2miles per minutes

Therefore in 1 hour that is 60 minutes the distance she will cover is

distance= velocity * time

Distance= 0.2*60

Distance= 12 miles

definitely a. the others have almost all data points on one side of the line.
