You look up and see a helicopter pass directly overhead: 3.10-s later you hear the sound of the engines. If the air temperature is 23.0°C, How high was the helicopter flying?

Answer 1

height=velocitysound*time

so figure the velocity of sound at 23C

Answer 2

1068.88m

Answer 3

d=distance v=velocity t=time

d = vt

331+0.6 (23) = 354.6

354.6 * 3.10 = 1068.88m
