Hey there!
The answer is 1 1/8 mile.To find the amount of miles Sarah ran, we need to multipy the length of the track by the times she run that distance.

Rembember: multiplying a fraction means you have to multiply the
numerator by the numerator (of the other fraction) and the denominator by the denominator (of the other fraction)
The answer is 1 1/8 mile.
