354632 When two sound waves travel in the same direction in a medium, the displacements of a particle located at ' \(x\) ' at time ' \(t\) ' is given by : \(y_{1}=0.05 \cos (0.50 \pi x-100 \pi t)\)
\(y_{2}=0.05 \cos (0.46 \pi x-92 \pi t)\)
where \(y_{1}, y_{2}\) and \(x\) are in meters and \(t\) in seconds. The speed of sound in the medium is :

1 \(92\;m/s\)
2 \(200\;m/s\)
3 \(100\;m/s\)
4 \(332\;m/s\)
