Problem of the Day

Chapter 6, Lesson 6

Since light travels faster than sound, you see a bolt of lightning before you hear the associated thunder. The distance between you and the place that you see a lightning bolt strike is in direct proportion to the time it takes for you to hear the associated thunder sound.

Two meteorologists, Ken and Jane, were standing in a direct line with a tree hit by a bolt of lightning, with Ken closer to the tree. Ken was standing 4000 feet from the tree and heard the sound 4 seconds after the lightning hit. Jane heard the sound 2 seconds later.

Write and solve a proportion that can be used to find Jane's distance from Ken.
