Question

Hose A can fill a bucket in 2 minutes and hose B can fill the same bucket in 3 minutes. How long would it take to fill the bucket if both hoses were used at the same time?

Answer 1

Answer:

1.2 minutes or 1 minute and 12 seconds.

Step-by-step explanation:

Hose A fill 1/2 bucket per minute

Hose B fill 1/3 bucket per minutes

So, if both hoses open, it will fill the bucket in:

1/(1/2+1/3) = 1 / (3/6 + 2/6) = 1/(5/6)  = 6/5 or 1.2 minutes

Therefore, both hoses open, it will fill the bucket in 1.2 minutes or 1 minute and 12 seconds.
