Answer 1

`13(7)/(16)` laps can Fred run in one hour.

Explanation:

Given Statement: Fred is running on the school track. He can run
`10(3)/(4)` laps in
`(4)/(5)` of an hour.

Unit rate are expressed as a quantity of 1, such as 3 feet per second or 7 miles per hour, they are called unit rates

From the given condition we have;

In
`(4)/(5)` he can run
`(43)/(4)` laps

Unit rate per hour =
`((43)/(4) )/((4)/(5) )`

=
`(43)/(4) * (5)/(4) = (215)/(16)` laps

Therefore, Fred can run in one hour is,
`13(7)/(16)` laps.
