    22. The speed s = 330 meters per seconds

    24. The speed s = 320 meters per seconds

    Step-by-step explanation:

    * Lets explain how to solve the problem

    - The equation s = 20√273 + T is used to estimate the speed of

    sound in meter per second for each Celsius temperature T

    - We will estimate square roots to the nearest tenth

    * Lets solve the problem

    22. T = 0° C

    - Substitute the value of T in the equation by 0

    ∵ s = 20√273 + T

    ∴ s = 20√273 + 0

    - The value of √273 is 16.5 to the nearest tenth

    ∴ s = 20 (16.5) = 330 meters per seconds

    ∴ The speed s = 330 meters per seconds

    24. T = - 10° C

    - Substitute the value of T in the equation by - 10

    ∵ s = 20√273 + T

    ∴ s = 20√273 + (-10)

    ∴ s = 20 (16.5) - 10 = 320 meters per seconds

    ∴ The speed s = 320 meters per seconds
