An ultrasound emitted from a substance returns after striking an obstacle in 10 seconds, the distance of the obstacle from the submarine if the velocity of sound in water is 1500m/s is 7500m.

1. The time taken for the sound to reach the obstacle is 10/2 = 5sec.

2. Velocity of sound in water = 1500m/s.

3. Distance of the obstacle from the submarine = velocity × time = 1500 × 5 = 7500m.
