Gabby placed three empty containers side by side. The smallest container has a crack at its side and the base area of each container is 25 cm2. After she turned on the tap for 60 minutes, the height of the water in the smallest container became 3 cm although 0.3 mℓ of water is leaking out of the crack per minute. Find the rate of flow of water from the tap. Give your answer in mℓ/min.
