Answer:
1760 fpm
Step-by-step explanation:
First, let's convert our mph to feet per hour.
20 miles per hour
Since 1 mile is 5280 feet, we can multiply 20 by 5280 to get the number of feet per hour.
20 * 5280 = 105600
20 mph = 105600 fph
To get this in feet per minutes, we just need to divide by 60. If we get 105600 feet in one hour, we'd get 105600/60 each minute.
105600 / 60 = 1760
Thus, 20 mph = 1760 feet per minute.
