Math CentralQuandaries & Queries


Question from Nedra, a parent:

If I walk 1 mile and 2/10ths in 20 minutes how fast am I going?
AND how many calories have I burned off?


There are 60 minutes in an hour so 20 minutes = 20/60 = 1/3 hours. Thus at the same speed you would go three times as far in an hour, which is

3 × 1 2/10 = 3.6 miles.

Thus you are walking at 3.6 miles per hour.

I have no idea how many calories this would burn.
