To solve the problem, we will use the Doppler effect formula for sound. The situation involves two buses moving towards each other, with one emitting a sound (the horn) and the other receiving it. ### Step-by-Step Solution: 1. **Convert Velocities from km/hr to m/s:** - For bus X: \[ V_1 = 120 \text{ km/hr} = \frac{120 \times 1000}{3600} = 33.33 \text{ m/s} ...
