An empty rectangular container has a capacity of 76 ℓ and a height of 50 cm. At 10 a.m., Tap S is turned on to fill the container at a rate of 10 ℓ per minute for 19 minutes. After 10 minutes, Tap T is turned on to drain water from the container at a rate of 6 ℓ per minute for 7 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 
10 ℓ = 10000 cm³ 
6 ℓ = 6000 cm³ 
76 ℓ = 76000 cm³

Volume of water flowed in from Tap S
= 19 x 10000
= 190000 cm³

Volume of water from drained from Tap T
= 7 x 6000
= 42000 cm³

Volume of water left in the container
= 190000 - 42000
= 148000 cm³

Base area of the container
= 76000 ÷ 50
= 1520 cm² 

Height of water left in the container
= 148000 ÷ 1520
≈ 97.4 cm

Answer(s): 97.4 cm
