The speed of a sound wave in air depends on the air temperature. The formula above (a = 1052 + 1.08*t) gives the speed a, in feet per second, when t is the temperature in degrees Fahrenheit. Which expresses air temperature in terms of speed?

At = 1.08 / (a + 1052)
Bt = (a - 1052) / 1.08
Ct = (a + 1052) / 1.08
Dt = (1052 - a) / 1.08
Answer & Solution
Correct answer: B. t = (a - 1052) / 1.08
Solve a = 1052 + 1.08*t for t. Subtract 1052: a - 1052 = 1.08*t. Divide by 1.08: t = (a - 1052) / 1.08.
