Respuesta :

Answer:

I think the answer is D (The water in the tank is decreasing at a rate of 5 gallons per minute).

Step-by-step explanation:

As we can see here, the water in the tank is decreasing at a rate of 10 gallons per 2 minutes.

That would be 2/10. Reduce 2/10 and you will get 1/5. So the final answer would be that the water in the tank is decreasing at a rate of  5 gallons per minute.
