Which of the following triangles are impossible to draw? Choose all that apply.

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
