Answer 2

Distance traveled in water in 2 seconds = 3.2 Km

Distance traveled in air in 5 seconds = 17.5 Km

Explanation:

Speed of sound in air = 350 ms–1

Speed of sound in water = 1600 ms–1

(i) Distance covered in 2s in water.

Distance = speed * time

= 1600 * 2

= 3200 m

= 3.2 Km

(ii) Distance covered in 5s in air.

Distance = speed * time

= 350 * 5

= 17500 m

= 17.5 Km
