In this unit, you were introduced to the following equation that, when the temperature "T" is known, you can determine the speed of sound in air:

v=20.1T

If you were asked to determine the air temperature at which the speed of sound is 335 m/s, which of the following steps to solving this problem would you use?

Group of answer choices

1. Divide both sides of the equation by 20.1, then square both sides.
2. Divide both sides of the equation by the square root of T, then multiply both sides by 20.1.
3. Multiply both sides of the equation by 20.1, then take the square root of both sides.
4. Divide both sides of the equation by the speed, then square both sides.
