Question

Eduardo counted ten seconds (y) between seeing lightning and hearing thunder, and he knew that the lightning was about 2 miles (x) away. What is the equation of the variation?

Answer 1

The equation for the variation is:

`(Miles)/(thunder\,\,time ) =0.2\,(mi)/(s)`

Explanation:

The relationship is given by the quotient between the two variables: (1) distance of the storm, and (2) the number of seconds to hear the thunder. That is:

`(Miles)/(thunder\,\,time ) =(2)/(10) =0.2\,(mi)/(s)`
