| DIRECT
VARIATION |
|
Let’s look at an example
of direct variation: an ocean wave breaking.
The height “h” (in feet) at which an ocean wave breaks
varies directly with the wave length “l” (in feet), which
is the distance from the crest of one wave to the crest
of the next. A wave that breaks at a height of 2 feet has
a wave length of 14 feet.
What is the wave length of a wave that breaks at a height
of 5 feet?
