Math CentralQuandaries & Queries


Question from Susann:

How long will it take to go 1 mile at 80 mph?
How do you work this problem?


If you go 80 miles in one hour then you go one mile in one-eightieth of an hour. Thus it takes 1/80 hours to go one mile. You can convert to a decimal and say that you go one mile in 0.0125 hours but it is probably to give the time in minutes. There are 60 minutes in 1 hour so how many minutes are in 1/80 of an hour?
