Answer 2

Mario’s average speed is 8 miles per hour.

Solution:

It is given that Mario runs 24 miles in 3 hours. We have to find what is Mario’s average speed in miles per hour.

In other words we have to find how much mile did Mario run in 1 hour. To find his average speed in miles will use the unitary method.

Using Unitary method,

In 3 hours Mario can run 24 miles.

In 1 hour Mario can run
`(24)/(3)` miles.
