  1. The sound velocity depends on temperature as
    v (meters per second)=20.046•sqroot(T)
    where T is absolute temperature (in Kelvins),
    or
    v(meters per second) = 331.4+0.6•t,
    where t is the temperature in degrees centigrade
    100F = 37.78 degrC
    v = 331.4+0.6 •37.78=354.06 m/s.
    1 mile =1 609 m.
    t = s/v = 1 609/354.06 =4.54 s

  2. What is the actual formula you are using? I cannot tell what you mean when you say "v=331.4 +0.6t". I want to actually learn how to do it.

  4. That is the actual formula, worth memorizing. Vsound= 331.4+.6T, T in Celcius.
