<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
miles in
of an hour.
of an hour = 4
miles
=
miles

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