Atrain blows its whistle as it enters a 50 m long tunnel. what is the time delay heard by a person at the other end of the tunnel between the sound of the train's whistle through the rails and through the air? assume that the speed of sound in the air and steel are 342 m/s and 5960 m/s respectively. i probably know how to answer this but i just don't understand what the question is saying and what i'm supposed to do.
