Hello,
I am kind stuck on this question
In the lab you discover a relationship between the temperature of the air and the speed of sound. You find the speed of sound is never lower than 331 m/s and increases by 60% of the current temperature.
a. What is the equation from this relationship?
b. If the temperature is 300 C, what is the speed of sound?
c. If the speed of sound is 391 m/s, what must be the temperature?

s = 331 + .6t
s(300) = 331 + .6(300) = 331 + 180 = 511
391 = 331 + .6t
60 = .6t
100 = t
