Question
The boiling point of water at sea level is 212 degrees Fahrenheit ( ∘F). For every increase of 1,000 feet above sea level, the boiling point of water drops approximately 1.84∘ F. Which of the following equations gives the approximate boiling point B, in ∘F, at h feet above sea level?
- B = 212 - 1.84h
- B = 212 - (0.00184)h
- B = 212h
- B = 1.84 (212) - 1,000h
The correct answer is: B = 212 - (0.00184)h
HINT: From the information provided, frame the equation.
Complete step by step solution:
Given that, boiling point of water at sea level = 212°F
Drop of boiling point of water for every increase of 1000 feet = 1.84°F
So, drop of boiling point at height h = 
(1.84)
Hence approximate boiling point (B) at h feet above sea level = 
(1.84)
So, B = 212 - (0.00184) h
Hence option B is the correct answer
