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

melomori [17]

$\frac{20 meters}{1 second} \frac{60 seconds}{1 minute} \frac{60 minutes}{1 hour}$

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
