Harris has two pipes to fill his aquarium. pipe a can fill the aquarium at the rate of 4 gallons per minute. pipe b can fill the aquarium at the rate of 840 liters per hour.
[1 gallon = 3.79 liters]
part b: if the total volume of the aquarium was 500 gallons and you checked on how full it was every 0.25 hours, describe appropriate scales on the x-axis and y-axis to graph the rate at which the faster pipe fills the aquarium.
