(13%) Problem 1: You are hiking along a trail in a wide, dry canyon where the outdoor temperature is I = 30.5 C. To determine how far you are away from the canyon wall you yell "Hello" and hear the echo t = 2.6 s later. Randomized Variables I = 30.5 C t = 2.6 s 33% Part (a) Calculate the speed of sound in the valley in meters per second, assuming the speed at 0 C is 332 m/s.
