One craftsperson can complete an order in 6 hours, and another can complete it in 3 hours. How many hours will they need to complete the same order if they work together at constant rates?
Show hints
- Add the fractions of the order completed by the two people in one hour.
- If half the order is completed in one hour, find the time needed for the whole order.
Show the answer and solution
Answer: 2
In one hour, the first person completes one sixth of the order and the second completes one third. Together they complete half the order per hour, so the full order takes 2 hours.
