Jasmine can run 4 5/6 miles in 2/3 of an hour. how many miles can she run in one hour
Jlenok [28]

Jasmine can run in one hour is 7.25 miles.

<h3>What is the formula of unitary method?</h3>

The formula of the unitary method is to find the value of a single unit and then multiply the value of a single unit to the number of units to get the necessary value.

Given that,

Jasmine can run 4\frac{5}{6} miles in \frac{2}{3} of an hour.

\frac{2}{3} of an hour = 4\frac{5}{6} miles

                     = \frac{29}{6} miles

By using unitary method we will find the value of an hour.

1 hour = \frac{\frac{29}{6} }{\frac{2}{3} }

          =  \frac{29}{6} × \frac{3}{2}

          = \frac{29}{4}

1 hour  = 7.25 miles

Hence, Jasmine can run in one hour is 7.25 miles.
