Question

Which variation is represented by this situation:

If one hose can fill a swimming pool in 7 hours, how long will it take 3 hoses to fill the pool?

Answer 1

2.3 hours.
7/3=2.3 hours
You do this because by taking the original total time, you divide it by 3 as it’s getting cut into 1/3 because there’s 3 instead of 1.
