Use the graph below to determine how many miles the car traveled in one hour

Divide 450 (miles) by 6 (number of hours) to get 75 miles in one hour

The car traveled 75 miles in one hour. To get this answer you take any point from the graph such as (6,450) and set it up as 450/6. Then next to it you put = and set up a fraction with one as the denominator and nothing as the numerator. We are trying to figure out how many miles the car traveled in one hour so our numerator is unknown. You cross multiply 450*1 and divide that by 6. You should can 75 as your answer which means that the car traveled 75 miles in one hour.
