An empty rectangular tank has a capacity of 182 ℓ and a height of 70 cm. At 10 a.m., Tap J is turned on to fill the tank at a rate of 7 ℓ per minute for 16 minutes. After 10 minutes, Tap K is turned on to drain water from the tank at a rate of 2 ℓ per minute for 22 minutes. What is the height of the water level in the tank in the end? Give the answer in 1 decimal place.
1 ℓ = 1000 cm³ 
7 ℓ = 7000 cm³ 
2 ℓ = 2000 cm³ 
182 ℓ = 182000 cm³

Volume of water flowed in from Tap J
= 16 x 7000
= 112000 cm³

Volume of water from drained from Tap K
= 22 x 2000
= 44000 cm³

Volume of water left in the tank
= 112000 - 44000
= 68000 cm³

Base area of the tank
= 182000 ÷ 70
= 2600 cm² 

Height of water left in the tank
= 68000 ÷ 2600
≈ 26.2 cm

Answer(s): 26.2 cm
