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
