The speed of sound in air is about 332 meters per second (sm) at 0 degrees Celsius (∘C). If the speed increases by 0.6sm for every increase in temperature of 1∘C, which inequality best represents the temperatures, T, in degrees Celsius, for which the speed of sound in air exceeds 350sm ?
Q. The speed of sound in air is about 332 meters per second (sm) at 0 degrees Celsius (∘C). If the speed increases by 0.6sm for every increase in temperature of 1∘C, which inequality best represents the temperatures, T, in degrees Celsius, for which the speed of sound in air exceeds 350sm ?
Given Information: We are given that the speed of sound in air at 0 degrees Celsius is 332 meters per second and that it increases by 0.6 meters per second for every 1 degree Celsius increase in temperature. We need to find the temperature at which the speed of sound exceeds 350 meters per second. Let's denote the temperature in degrees Celsius as T and the speed of sound in meters per second as S(T). The relationship between the speed of sound and the temperature can be expressed as:S(T)=332+0.6T
Speed of Sound Inequality: To find the temperature at which the speed of sound exceeds 350 meters per second, we need to solve the inequality:S(T) > 350Substituting the expression for S(T) from the previous step, we get:332 + 0.6T > 350
Solving the Inequality: Now, we solve the inequality for T:0.6T > 350 - 3320.6T > 18
Isolating T: Divide both sides of the inequality by 0.6 to isolate T: T > \frac{18}{0.6}T > 30
Final Temperature Range: The inequality T > 30 represents the temperatures in degrees Celsius for which the speed of sound in air exceeds 350 meters per second.
