Which Plane___________rate______________time________________distance
First Fast____________3r________________2___________________3r*2
Second Slower__________r________________2___________________r*2
Their Difference________________________2___________________368
One plane went farther than the other creating distance between them of 368 miles. The difference from "distance" column expressions is . Obviously showing the subtraction of the slower plane distance from the faster plane distance is most sensible. Solve for r. Compute 3r.
Note, equation simplifies to .
