Question

If you are driving 20 meters per second, what would be the equivalent of that in miles per hour?

Answer 1

`(20 meters)/(1 second) (60 seconds)/(1 minute) (60 minutes)/(1 hour)`

the fractions are set up so that each unit cancels out until its only meters/hour

you can multiply all the numerators together to get 72000 and all the denominators to get 1

72000 meters/1 hour

72000 meters in 1 hour

hope this helped
