A can do a piece of work in 13 days and B in 25 days. In how many days can they complete it together?
Answer:
8.55
Step-by-step solution: 1. A's work rate = 1/13. 2. B's work rate = 1/25. 3. Combined rate = 1/13 + 1/25. 4. Time = 1 / combined rate = 8.55 days.
539
A can do a piece of work in 15 days and B in 24 days. In how many days can they complete it together?
Answer:
9.23
Step-by-step solution: 1. A's work rate = 1/15. 2. B's work rate = 1/24. 3. Combined rate = 1/15 + 1/24. 4. Time = 1 / combined rate = 9.23 days.
540
A can do a piece of work in 17 days and B in 25 days. In how many days can they complete it together?
Answer:
10.12
Step-by-step solution: 1. A's work rate = 1/17. 2. B's work rate = 1/25. 3. Combined rate = 1/17 + 1/25. 4. Time = 1 / combined rate = 10.12 days.
