Intermediate algebra

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?

• Intermediate algebra -

s = 331 + .6t

s(300) = 331 + .6(300) = 331 + 180 = 511

391 = 331 + .6t
60 = .6t
100 = t

A bat emits a sound whose frequency is 83.2 kHz. The speed of sound in air at 20.0 oC is 343 m/s. However, the air temperature is 40.5 oC, so the speed of sound is not 343 m/s. Assume that air behaves like an ideal gas, and find the …
