Beats calculation/Doppler Effect

[Dilman Sidhu]

Homework Statement

Person stands midway btwn two out of tune bagpipers. f1= 258 Hz and f2= 262 Hz. the speed of sound is 340 m/s. The individual does not want to hear beats, how fast and in which direction should she run so that the frequencies she hears from the two bagpipers are the same? What is this frequency she hears?

Homework Equations

Doppler Effect?

The Attempt at a Solution

I am unsure how to go about solving this equation. I have solved the Doppler Effect in the scenario when either the source or observer or both are moving and need to determine the change in frequency. Put am unsure how to apply that knowledge to this equation.
