Container A has 200 L of water, and is being filled at a rate of 6 liters per minute. Container B has 500 L of water, and is being drained at 2 liters per minute. How many minutes, m, will it take for the two containers to have the same amount of water?
Which equation best represents the situation above?
1. 200 + 500 = 2m + 6m
2. 200 - 2m = 500 - 6m
3. 700 = 8m
4. 500 - 2m = 200 + 6m
