Answer:
25 minutes
Step-by-step explanation:
Let the amount of time, in minutes, be x.
For Container A, we can write:
200 + 6x [since it has 200 and is being filled with 6 per minute]
For Container B, we can write:
500 - 6x [since it has 500 and is being drained with 6 per minute]
To find, we equate them and solve for x:
[tex]200+6x=500-6x\\6x+6x=500-200\\12x=300\\x=\frac{300}{12}\\x=25[/tex]
So, in 25 minutes (m), the two containers will have same amount of water
