The speed of sound in air (in m/s) depends on the temperature according to the approximate expression below, where TC is the Celsius temperature. In dry air the temperature decreases about 1°C for every 150 m rise in altitude. v = 331.5 + 0.607TC (a) Assuming this change is constant up to an altitude of 9000 m, how long will it take the sound from an airplane at 8800 m to reach the ground on a day when the ground temperature is 32°C? s

The speed of the sound in air is approximately v=331.4 m/s + (0.6 m/c⋅C)T where T is the temperature in degrees Celsius. The speed of the light is 300000 km/s. The speed of the light is so large that in practical terms, involving distances on Earth, the light travels instantly. On a cool night with air temperature of about 10∘C, you see a lightning flash and then hear the thunder rumble five seconds later. How far is the lightning strike?
