Combined rates
Given that Haley and Samuel can each make one gift box in two hours, while Rachael takes three hours to make the gift box alone, to determine, if Haley, Samuel, and Rachael work together, how long will it take them to make one gift box, the following calculation must be performed, using combined rates:
- 1/2 + 1/2 + 1/3 = X
- 3/6 + 3/6 + 2/6 = X
- 8/6 = X
- 6/6 = 1 hour
- 8/6 = 40 minutes
Therefore, it will take 40 minutes for them to make one gift box.
