First, we need to find the number of degrees above 0 degrees Fahrenheit to calculate the increase in speed of sound.

67 degrees Fahrenheit - 0 degrees Fahrenheit = 67 degrees

Now, we can use the given formula to calculate the increase in speed of sound:

67 degrees x 1.1 feet per second per degree = 73.7 feet per second

Finally, we add this increase to the speed of sound at 0 degrees Fahrenheit:

1052.3 feet per second + 73.7 feet per second = 1126 feet per second

Therefore, the speed of sound at 67 degrees Fahrenheit is 1126 feet per second, which is answer choice D.

The Speed of Sound at 0 Degrees Fahrenheit Is 1052
