A railway engine is 3300m away from a boy. The boy places one ear on the steel rail and also listens through the air. He hears the whistle through the rail 8s before he hears it through the air (speed of sound in air =330m/s).
a. (i) Calculate the speed of sound in the steel rail.
b. (ii) Find the ratio of the speed of sound in steel to that in air.
