To convert the speed of pickleball from miles per hour (mph) to feet per minute (fpm), we can use the following conversion factors:
1 mile = 5280 feet
1 hour = 60 minutes
First, we start with the speed of 100 mph:
\[ 100 \text{ mph} \times \frac{5280 \text{ feet}}{1 \text{ mile}} \times \frac{1 \text{ hour}}{60 \text{ minutes}} \]
Now we do the calculations:
\[ 100 \times 5280 = 528000 \text{ feet per hour} \]
Now converting feet per hour to feet per minute:
\[ \frac{528000 \text{ feet}}{60 \text{ minutes}} = 8800 \text{ feet per minute} \]
Therefore, the speed of pickleball in feet per minute is 8800 feet per minute.
