A airplane approaches at an altitude of 10 km flying at 600 km/hr. 1. If the air temperature at that altitude is -50 °C, what is the speed of sound in air there? 2. How does that differ from the speed of sound in air typically at Earth's surface? 3. If the plane will be overhead in 1 minute, when will we hear it coming? You may assume an average speed along the path from the plane to your ear. THE ANSWER TO QUESTION 3 PLEASE
