In 20 minutes a person runs 2.2 miles
In 1 minute the person runs = 2.2/20 miles
In 60 minutes the person runs = (2.2/20) * 60
                                                 = 2.2 * 3 miles
                                                 = 6.6 miles
Then the person travels at a rate of 6.6 miles/hour.
