An empty rectangular container has a capacity of 62 ℓ and a height of 80 cm. At 6 a.m., Tap M is turned on to fill the container at a rate of 2 ℓ per minute for 15 minutes. After 15 minutes, Tap N is turned on to drain water from the container at a rate of 2 ℓ per minute for 13 minutes. What is the height of the water level in the container in the end? Give the answer in 1 decimal place.
1 ℓ = 1000 cm³ 
2 ℓ = 2000 cm³ 
2 ℓ = 2000 cm³ 
62 ℓ = 62000 cm³

Volume of water flowed in from Tap M
= 15 x 2000
= 30000 cm³

Volume of water from drained from Tap N
= 13 x 2000
= 26000 cm³

Volume of water left in the container
= 30000 - 26000
= 4000 cm³

Base area of the container
= 62000 ÷ 80
= 775 cm² 

Height of water left in the container
= 4000 ÷ 775
≈ 5.2 cm

Answer(s): 5.2 cm
