Question

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?

Answer 1

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
