It would take Joe and Sam 1.875 hours (or 1 hour and 52.5 minutes) to paint the house together. This is found by using the formula: 1/3 + 1/5 = 8/15 This means that together, Joe and Sam can complete 8/15th of the job in one hour. To find the total time it takes to complete the whole job, we divide 1 by 8/15: 1 ? 8/15 = 1.875 or 1 hour and 52.5 minutes.
