What is the relationship between miles per hour (mph) and feet per minute (fpm)?

To understand the relationship between miles per hour (mph) and feet per minute (fpm), it's helpful to know the conversions involved in moving from one unit of measurement to another.

1 mile is equal to 5,280 feet, and there are 60 minutes in an hour. Therefore, to convert mph to fpm, you would use the following conversion:

1 mph = (5,280 feet/mile) / (60 minutes/hour)

Calculating this results in:

1 mph = 5,280 feet / 60 minutes = 88 feet per minute.

Thus, the correct answer is indeed that 1 mph equals 88 feet per minute. This relationship is vital for understanding different speeds in terms of various measurements, making it useful in fields such as transportation, engineering, and environmental science, including aquatic weed control assessments.
