You are hiking along a trail in a wide, dry canyon where the outdoor temperature is T 30.5° C. To determine how far you are away from the canyon wall you yell  "Hello" and hear the echo t = 3.3 s later.

Randomized Variables

T = 305° C

t = 3.3 s

Part (a) Calculate the speed of sound in the valley in meters per second, assuming the speed at 0° C is 332 m/s

Numeric: A numeric value is expected and not an expression.

v = ___________

Part (b) How far are you from the canyon wall, in meters?

Numeric: A numeric value is expected and not an expression.

D = ___________

Part (c) If you stood at the same point on a cold morning where the temperature was T= -7.5 degrees C, how long would it have taken for you to hear the echo, in seconds?

Numeric: A numeric value is expected and not an expression.

t2 =  ___________
