(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A stationary whistle emits a sound of 190 Hz. If a car hears the whistle with a frequency of 198 Hz, how fast was it moving (in m/s)? Use 340 m/s for the sound velocity

2. Relevant equations

f'=(1+Vo/V)f ======>>>> equation for the observer moving toward stationary source.

3. The attempt at a solution

f'=(1+Vo/V)f

198=(1+Vo/340)190

please help! what am i doing wrong?
