Question

Cindy roller skates 30 miles in 225 minutes. What is her average speed in miles per hour?

Answer 1

8 mph

Explanation:

To find the average speed in mph, use the formula:

`(distance)/(time)` or in this case
`(miles)/(hours)`.

We have to convert the minutes to hours, so 225 minutes is equivalent to 3 3/4 hours.

30/3.75

=8

So she travels at 8mph.

Hope this helps! :)
