[tex]\frac{240 inches}{1 minute}[/tex]
We're going to change one unit at a time. Let's start with inches to feet. There are 12 inches in 1 foot. Divide 240 by 12 or multiply by 1/12.
[tex]\frac{240 inches}{1 minute} * \frac{1 foot}{12 inches}=\frac{20 feet}{1 minute}[/tex]
Next, let's do the time using the same idea. Remember that there are 60 minutes in 1 hour.
[tex]\frac{20 feet}{1 minute} * \frac{60 minutes}{1 hour} = \frac{1200feet}{1hour}[/tex]
Answer: 1200 feet per hour
Hope this helps!
