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.
