3 people can build a shed in 8 hours, how long would it take 5 people

3 people can build a shed in 8 hours, how long would it take 5 people

We set up a proportion of people to hours where h is the number of hours for 5 people:
3/8 = 5/h

Using our proportion calculator, we get:
13.3333 hours

But what if the problem asks for minutes? Then we say 8 hours = 60 * 8 = 480 minutes. We set up the proportion where m is the number of minutes:
3/480 = 5/m

In this case, we use our search engine again and get:
m = 800
