According to data from the Hill AerospaceMuse um (Hill Air Force Base, Utah), the speed of sound varies depending on altitude, barometric pressure, and temperature. For example, at 20,000 feet, 13.75 inches ofmercury, and - 12.3°F, the speed of sound is about 707 miles per hour, but the speed can vary from this result by as much as 55 miles per hour as conditions change.(a) Express this situation as an inequality involving an absolute value.(b) Using x for the speed of sound, solve for x to find an interval for the speed of sound.
