Question 1174866: It takes you 3 hours working alone to clean your apartment, and your spouse takes 6 hours and 30 minutes. If you work together, how long will it take to complete the cleaning?
You can put this solution on YOUR website! Your rate working alone = 1/3 of the apartment per hour
Your spouse's rate working alone = 1/6.5 of the apartment per hour
Rate working together = 1/3 + 1/6.5 = 1/3 + 2/13 = 13/39 + 6/39 = 19/39
If, working together, 19/39 of the apartment is cleaned per hour, this means it takes 39/19 hours to clean the apartment working together.
