The pilot of a plane flying 5000 feet above sea level observes two ships in line due east.
The measurements of the angles of depres-
sion are 30% and 39º. How far apart are the
ships?

The boiling point of water at an elevation of 0 feet is 212 degrees fahrenheit (°f). for every 1,000 feet of increase in elevation, the boiling point of water decreases by about 2°f. which of the following represents this relationship if b is the boiling point of water at an elevation of e thousand feet? a) e = 2b - 212 b) b = 2e - 212 c) e = -2b + 212 d) b = -2e + 212
