Answer:
Both buckets will have the same amount of water after 25 minutes
Step-by-step explanation:
Equations
Let's call:
t = number of minutes elapsed for both buckets
The red bucket already has 200 L of water and it's flowing in at a rate of 6 liters per minute. Thus, the volume of water in this bucket is:
R = 200 + 6t
The blue bucket has 500 liters of water and is being drained at 6 liters per minute. The volume can be modeled by the equation:
B = 500 - 6t
The condition for both buckets to have the same amount of water is:
R = B
200 + 6t = 500 - 6t
Adding 6t and subtracting 200:
6t + 6t = 500 - 200
12t = 300
t = 300/12
t = 25 minutes
Both buckets will have the same amount of water after 25 minutes
