Question

Anna runs 3/4 miles in 6 minutes or 1/10 hour. assuming she runs at a constant rate, what is her speed, in miles per hour?

Answer 1

We will use the equation $distance=rate*time$ to solve this one. We have distance and time, so we'll rearrange this to:
$r=\frac{d}{t}=\frac{\frac{3}{4}}{\frac{1}{10}}=\frac{3}{4}*\frac{10}{1}=\frac{30}{4}=\frac{15}{2}=7.5$

So she runs 7.5 miles per hour.
