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.
![1 (1)/(2) * (3)/(4) = (3)/(2) * (3)/(4) = (9)/(8) = 1 (1)/(8)](https://img.qammunity.org/2019/formulas/mathematics/college/5h1b5r396rdfak14muemqhuq189jcvlq79.png)
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.
