Five men completed a task in 36 hours and 45 minutes. How long in hours and minutes would it take three men to complete the same task?

The easiest way for me to do this is by the mins.

There are 60 mins in 1 hour so do 36 x 60

then add 45

so you're working with 2,205 mins. So let's divide by the 3 men instead ...

735 now lets reverse engineer this ...

735 / 60 (mins)

12 hours 25 mins ...

now lets add that to our original ...

49 hours and 5 mins.

I could be wrong but as far as I'm looking at it seems like a good way to answer. anyone is welcome to check my work.

Another way to look at this is the same 2205 mins, but as a fraction 5/5 3/5

3/5 is. 60 percent of 5/5 so multiply 2205 by. 60

264.6

now divide by 60 4.41

Now add to first ...

41 hours 43 mins
