If a person runs 1 3 mile in 1 9 of an hour, what is the unit rate per hour?

When dividing a fraction by a fraction, we keep the first fraction the way it is, change our division into multiplication and flip the second fraction (which is multiplying by the reciprocal).

=1/3 × 9/1

=9/3

=3 miles per hour

The person's speed is 3 miles per hour.

If 1 hour is 3 miles, then 1/9 of an hour is 1/3 mile.
