Direct variation application | Rational expressions | Algebra II
In outer space the distance an object travels varies directly with the amount of time that it travels. If an asteroid travels 3000 miles in 6 hours what is the constant of variation?
Inverse variation application | Rational expressions
On a string instrument the length of a string varies inversely as the frequency of its vibrations (the vibrations are what give string instruments their sound). An 11-inch string has a frequency of 400 cycles per second. Find the constant of proportionality and then find the frequency of a 10-inch string.
