Question 1 • Reading HS- Integrated Math I
Alex removes 1 gallon from the full 5-gallon tank, so 4 gallons—or 4/5 of the tank’s volume—remain. In a cylindrical tank, the water height is proportional to its volume, so the remaining height is (4/5) × 2 feet = 1.6 feet. Converting to inches gives 1.6 × 12 = 19.2 inches, so the correct choice is 19.2 inches.
