HELP! - Water boils at different temperatures at different elevations. The boiling temperature of water is 212F at sea level (0 feet) but drops about 1.72F for every 1,000 feet of elevation. Write a formula for the boiling point at a given elevation. Then solve the formula for the elevation when the boiling point for water is 190F. Determine a formula for the boiling point b, in degrees Fahrenheit, at elevation h, in feet.

a. T = -1.72x + 212

b. 12,790 feet

Step-by-step explanation:

a. Let us assume the number of 1,000 elevation feet be x

Now the equation would be

T = -1.72x + 212

here the negative sign represents the fall in the boiling temperature with rise in elevation

b. Since the formula is

T = -1.72x + 212

can we write

T  - 212 = -1.72x

now divide by 1.72 in both the sides

x = 12.79

So in feets it should be

= 12.79 × 1,000 feets

= 12790 feet
