Final answer:
Without the rate of water flow into the tank, it is impossible to determine how many gallons of water will be in the fish tank after 4 minutes. Normally, the flow rate in gallons per minute is multiplied by the number of minutes to find the total volume, but this information is missing in the provided context.
Step-by-step explanation:
To determine how many gallons of water will be in the fish tank after 4 minutes, we need additional information such as the rate at which water is being filled into the tank. The information provided does not give us these details, hence it is impossible to accurately answer the question without further context. Normally, in problems like this, you would check the rate of water flow (gallons per minute) and multiply this rate by the amount of time (4 minutes in this case) to find the total volume of water added to the tank.
For instance, if we knew the flow rate was 1.5 gallons per minute, we could calculate the volume of water after 4 minutes by multiplying 1.5 gallons/minute by 4 minutes, which would give us 6 gallons (1.5 gallons/minute * 4 minutes = 6 gallons). However, since we do not have this particular detail, we cannot select an answer from the options provided (A. 2.67, B. 5, C. 6, D. 6.5).
