Stan and Ollie are standing next to a train track. Stan puts his ear to the steel track to hear the train coming. He hears the sound of the train whistle through the track 2.4 s before Ollie hears it through the air. How far away is the train? (Use 5,790 m/s as the speed of sound in steel and 343 m/s as the speed of sound in air.) m
