The speed of sound in air (in meters per second) depends on temperature according to the approximate expression v = 331.5 + 0.607 T where T is the Celsius temperature. In dry air, the temperature decreases about 1°C for every 150-m rise in altitude.

(a) Assume this change is constant up to an altitude of 9,000 m. What time interval is required for the sound for the sound from an airplane flying at 9,000m to reach the ground on a day when the ground temperature is 30°C?

(b) What if? Compare your answer with the time interval required if the air uniformly at 30°C. Which time interval is longer?
