A car at a velocity of `17 ms^(-1)` towards an approaching bus that blows a horn at a frequency of 640 Hz on a straight track. The frequency of this horn appears to be 680 Hz. To the car driver. If the velocity of sound in air is 340 ms^(-1), then the velocity of the approaching bus is

`2 ms^(-1)`

`4 ms^(-1)`

`8 ms^(-1)`

`10 ms^(-1)`
