Solve Applications with Rational Equations · Exercise 78

Write an inverse variation equation to solve the following problems.

On a string instrument, the length of a string varies inversely as the frequency of its vibrations. An 11-inch string on a violin has a frequency of 400 cycles per second.
ⓐ Write the equation that relates the string length to its frequency. ⓑ What is the frequency of a 10 inch string?

Its source prints no answer for this problem, so there's nothing to check against.
