Hi Denis

Many thanks for getting back to me, it's greatly appreciated. I'm at a total loss to be honest and don't know where to begin.
Is there a worked example or something you can point be towards?

How many "manhours" would it take to paint the room? (ie how many painting hours would it take in total to get the job done?)

Then think, if you need the job done in two hours, how many people must you have on the job?

It took (3 * 5 =) 15 people hours to paint a room.

How many people will be needed to get 15 people-hours in 2 hours?
