(10%) Problem 6: You place your ear onto a steel railroad track and hear the sound of a distant train through the rails At: 2.8 seconds faster than you do through the air. The speed of sound in steel is V; = 6100 m/s while in air the speed of sound is va = 343 m/s. E & 25% Part (3) Write an equation for the time it takes the sound to reach you through the air if the distance to the train is represented by D. & 25% Part (b) Write an equation for the time it takes the sound to reach you through the steel if the distance to the train is represented by D. & 25% Part (c) Use the difference in these two times to write an equation for the distance to the train. D A 25% Part ((1) For the given information nd the distance to the train in meters. Grade Summary D = Deductions 0 % 41mm
