Answer: 12 minutes
Step-by-step explanation:
This is a standard Work Formula question (2 or more 'entities' that work on a task together). When there are just 2 entities and there are no 'twists' to the question, we can use the Work Formula to get to the correct answer.
Work = (A)(B)/(A+B) where A and B are the individual times needed to complete the task.
We're told that two hoses take 20 minutes and 30 minutes, respectively, to fill a pool. We're asked how long it takes the two hoses, working together, to fill the pool.
(20)(30)/(20+30) = 600/50 = 12 minutes to fill the pool.
