Marion placed three empty containers side by side. The smallest container has a crack at its side and the base area of each container is 49 cm². After she turned on the tap for 63 minutes, the height of the water in the smallest container became 2 cm although 0.7 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.
Water that leaked from the crack
= 63 x 0.7
= 44.1 mℓ

Water that poured into the 3 containers
= 49 x (2 + 14 + 6 + 34 + 7)
= 49 x 63
= 3087 cm³ 
= 3087 mℓ

Total water that flowed from the tap
= 3087 + 44.1
= 3131.1 mℓ

Rate of water flow from the tap
= 3131.1 ÷ 63
= 49.7 mℓ/min

Answer(s): 49.7 mℓ/min
