We know that Aisha runs 1 kilometer in 7 minutes. We need to figure out how fast Sophia runs 1 kilometer, and compare that to Aisha's time.

Let's find the difference in time between 2 and 1 kilometers, and 3 and 2 kilometers.

21 - 15.5 = 5.5

26.5 - 21 = 5.5

Now, we know that Sophia runs 1 kilomenter in 5.5 minutes.

Aisha's equation: y = 7x (+ 0)

Sophia's equation: y = 5.5x + 10

Sophia runs faster because 5.5 < 7, so she runs 1 kilometer in 1.5 minutes less than Aisha does.

Hope this helps! :)
