Convert 30 miles to feet per minute
The correct answer and explanation is:
To convert 30 miles per hour (mph) to feet per minute, follow these steps:
- Convert miles to feet:
There are 5,280 feet in one mile. So, to convert miles to feet, multiply by 5,280. 30 miles×5280 feet/mile=158,400 feet30 \text{ miles} \times 5280 \text{ feet/mile} = 158,400 \text{ feet} - Convert hours to minutes:
There are 60 minutes in an hour. So, to convert miles per hour to feet per minute, divide the total feet by 60. 158,400 feet÷60 minutes=2,640 feet/minute158,400 \text{ feet} \div 60 \text{ minutes} = 2,640 \text{ feet/minute}
So, 30 miles per hour is equivalent to 2,640 feet per minute.
Explanation:
When converting between units of speed, you need to know the equivalent measurement in the units you’re converting from and to. In this case, you’re starting with miles per hour and want to convert to feet per minute.
The conversion process involves two key steps:
- Miles to feet: Since 1 mile equals 5,280 feet, you multiply the number of miles by 5,280 to get the total feet.
- Time units (hours to minutes): Since there are 60 minutes in an hour, dividing the total feet by 60 gives the speed in feet per minute.
This kind of unit conversion is commonly used when you want to express the same speed in different units to suit particular situations, such as understanding travel time or comparing speeds in different contexts. It’s important to recognize that while the speed may remain constant, the way it’s expressed can change based on the units used.
