Question

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

Use rates, so 8 garden hoses over 18 hours
then find the how many hours one garden house can fill up by doing this = 18/8 you divide the 8 for both sides which is about 2.25/1
so then you times 9 which is about 20/9 hoses
your answer is 20

Answer 2

Your answer would be 20 because you have to take 18 and divide it by 8 and add the answer you get to the 18 hours and there’s your answer.
