It takes 18 hours to fill a pool using 8 garden hoses. How long would it take to fill the same pool using 9 garden hoses

Answer 1

We can set up a proportion to solve this problem.

Let x be the number of hours it would take to fill the pool using 9 garden hoses.

We have the ratio: 18 hours / 8 hoses = x hours / 9 hoses

Cross-multiplying, we get: 8 * x = 18 * 9

Simplifying, we have: 8x = 162

Dividing both sides by 8, we get: x = 162 / 8

Therefore, it would take approximately 20.25 hours to fill the same pool using 9 garden hoses.
