    Answer:

    697 m

    Explanation:

    From the question above,

    Note: Alice hears the splash of the rock in the well through the help of echo.

    Applying,

    v = 2x/t…………………… Equation 1

    Where v = speed of sound, x = depth of the well, t = time.

    make x the subject of the formula in equation 1

    x = vt/2………………. Equation 2.

    Given: v = 340 m/s, t = 4.1 s

    Substitute these values into equation 2

    x = 340(4.1)/2

    x = 697 m.
