Answer 1

Answer:

$13\frac{7}{16}$ laps can Fred run in one hour.

Step-by-step explanation:

Given Statement: Fred is running on the school track. He can run $10\frac{3}{4}$  laps in $\frac{4}{5}$  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 $\frac{4}{5}$ he can run $\frac{43}{4}$ laps

Unit rate per hour = $\frac{\frac{43}{4} }{\frac{4}{5} }$

                              =$\frac{43}{4} \times \frac{5}{4} = \frac{215}{16}$ laps

Therefore, Fred can run in one hour is, $13\frac{7}{16}$ laps.
