Question

A cyclist rode 5.5 miles in 0.6 how fast was she going in miles per hour ?

Answer 1

To find average speed, there is a simple formula:

$\begin{gathered} v=\frac{x}{t} \\ \text{where, } \\ v=\text{speed} \\ x=\text{distance} \\ t=\text{time} \end{gathered}$

Then:

$\begin{gathered} v=\frac{5.5}{0.6} \\ v=9.166\text{ miles per hour} \end{gathered}$
