15/45 = x/60 * Cross multiply and solve for x x=20
If the ratio of minivans to total vehicles is 15 out of 45, then 20 minivans will pass Luann when 60 vehicles pass her. This is determined by setting up a proportion and solving for the number of minivans. The calculation involves cross-multiplication and division to find the final answer.
