2) You are hiking along a trail in a wide, dry canyon where the outdoor temperature is T = 32° C. To determine how far you are away from the canyon wall you yell “Hello” and hear the echo t = 3.5 s later. Randomized Variables T = 32° C t = 3.5 s a) Calculate the speed of sound in the valley in meters per second, assuming the speed at 0° C is 330 m/s. b) How far are you from the canyon wall, in meters? c) If you stood at the same point on a cold morning where the temperature was T2 = -3.5 degrees C, how long would it have taken for you to hear the echo, in seconds?
