A:### Quick Answer

To calculate minutes per mile, use the mathematical formula for rate (rate = distance/time). You need to know the distance traveled and the amount of time it took to travel that far.

Know More**Measure the amount of miles traveled**Make sure this measurement is in exact miles using standard form (no fractions). For example, if the distance is 10 1/2 miles, it should be written as 10.5.

**Determine the time it took to travel the above distance**This figure should be converted into minutes if it is not already. Multiply the number of hours by 60 (the number of minutes in an hour) to convert into minutes. If the time was 2 hours, you would multiply 2 by 60, which equals 120 minutes.

**Do the math**Divide the distance in miles by the time in minutes. For this example, 10.5 miles / 120 minutes = 0.0875 minutes per mile.

## How do you calculate the cost of electricity per hour?

A:

Full Answer >**Calculating the cost of electricity per hour is done by finding the kilowatt-hour.**Using 1,000 watts for one hour is a kilowatt-hour. The formula to get kilowatt-hours is to take the wattage of the device, multiply by number of hours used and divide by 1,000.Filed Under:
