Question

A runner runs at 7.6mph for 3 1/2 hours how many miles did he run

Answer 1

he ran 26 6/10 miles. 7.6x3.5=26.6. I hope this helps!

Answer 2

26.6 miles

Explanation:

Given: A runner runs at 7.6 miles per hour.

To find: The number of miles he can run in
`3(1)/(2)` hours.

Solution: To find the number of miles he can run in
`3(1)/(2)` hours. We first need to simplify
`3(1)/(2)`

So, we can write
`3(1)/(2)` as
`(7)/(2)`

Now, the speed of runner is 7.6 miles per hour. So, we can say that the runner can cover a distance of 7.6 miles in 1 hour.

To find the number of miles he ran we need to multiply the distance cover by the runner in 1 hour by
`(7)/(2)`

So, we have

`7.6*(7)/(2)`

`=(76)/(10)*(7)/(2)`

`=(7*38)/(10)`

`(266)/(10)`

`=26.6` miles

Hence, the runner can run 26.6 miles in
`3(1)/(2)` hour.
