Answer:

44.44 miles per hour.

Explanation:

A truck driver drove 300 miles in
6(3)/(4) hours.

We have to calculate the speed per hour.

First we convert
6(3)/(4) hours to decimal form.


6(3)/(4) = 6.75 hours

∵ in 6.75 hours the driver drove = 300 miles

∴ in 1 hour he drove =
(300)/(6.75) miles

= 44.44 miles

The truck driver drove 44.44 miles per hour.

44.4 miles per hour. You just divide 300 and 6.75 (Think as the 3/4 as quarters each 1 is .25) then you will get 44.4. To check your answer you would multiply 44.4 and 6.75 and get 299.7. This is not 300 but when you round that .7 to the nearest 10 you will get 300. Hope this helped.
