Writing and using
At sea level, the speed of sound in air is linearly related to the air
temperature. If it is 35˚C, sound will travel at a rate of 352 meters per
a linear model.
second. If it is 15˚C, sound will travel at a rate of 340 meters per second.
Write a linear equation that models the speed of sound s in terms of air
temperature t.
