You place your ear onto a steel railroad track and hear the sound of a distant train through the rails Δt = 3.4 sec….?

before soaring through the air. The speed of sound in steel is vs = 6100 m/s, and the air temperature is 23.5°C.

speed of sound in air
331m/s + 0.6m/sC
331 + 0.6 (23.5) = 345.1 m/s
the distance is assumed to be the same for both events
if the time on the rail is x then the time in the air is x + 3.4
345.1 m/s (x+3.4)s = 6100 m/s (x)s
345.1x + 1173.34 = 6100x
5754.9x = 1173.34
x = 0.204 s track time
then
6100 m/s * 0.204 s = 1243.7 m or approximately 1240 m
When you get a good answer,
please consider giving a better answer.
