Final answer:
To convert 21 miles per hour to feet per minute, multiply 21 by 5280 to get feet per hour, then divide by 60 to get feet per minute, resulting in 1848 feet per minute.
Step-by-step explanation:
To convert the speed of a go-cart from miles per hour to feet per minute, you can perform the following steps:
- Convert miles to feet knowing that 1 mile is equal to 5280 feet.
- Then, convert hours to minutes knowing that 1 hour has 60 minutes.
First, we multiply the speed of the go-cart (21 miles per hour) by 5280 feet per mile to get the speed in feet per hour. Next, we divide this result by 60 minutes per hour to find the speed in feet per minute.
Calculation:
- 21 miles/hour × 5280 feet/mile = 110,880 feet/hour
- 110,880 feet/hour ÷ 60 minutes/hour = 1848 feet/minute
Therefore, the go-cart travels at 1848 feet per minute.
