RE: [RC] Figuring MPH?  Mike SherrellIt helps if you have a calculator. First figure out how many hours you rode. Take the minutes and divide by 60, then add the number of hours. In your example this would give you 1.167 hours. Then divide that into the miles: 15 divided by 1.167 = 12.86 miles per hour. It may be easier to remember this by imagining you spent exactly one hour travelling, so if you went 15 miles in one hour, 15 miles divided by one is 15, and you went 15 miles per hour. If you spent two hours going 15 miles, it would be 15 divided by two, which is 7.5, so you went 7.5 miles per each hour. If you went 15 miles in three hours, it would be 15 divided by three, which is 5, so you went 5 miles in one hour.

I had a singing chemistry teacher in high school who taught us this. He called it "Uncle Carroll's fabulous fraction bar". Write 15 miles, draw a line under it. Under the line write 70 minutes. This is where you sing, but we don't want minutes (write minutes above the bar, leaving a space in front), we want hours (write hours under the bar). Now fill in the conversion rates i.e.. put 60 in front of the minutes because there are 60 minutes in an hour. Now cross out everything above and below the bar that is the same (minutes). You will now have: 15 miles 60 70 hours Multiply the # above the line and divide by the #s below the line and you have 12.85 mph.

Okay, so when it comes to mathematics, I am a mental midget. Could someone PLEEEEEEEEEEEASE tell me the formula for figuring average MPH? For instance, if I ride 15 miles in an hour and ten minutes, what was my average MPH? Go ahead, make fun of my shortcomings if you will, but please give me the formula? :o) Scott =================================== Ridecamp is a service of Endurance Net, http://www.endurance.net.
