give the standard mountain where A= 2,00 feet B = 12,000 feet and C = 4,000 feet. IF the temperature at A is 82 degrees F and the dew point temperature is 60 degrees F , what is the elevation in feet of X?

A standard temperature lapse rate is when the temperature decreases at the rate of approximately 3.5 °F or 2 °C per thousand feet up to 36,000 feet, which is approximately –65 °F or –55 °C. Above this point, the temperature is considered constant up to 80,000 feet.
