Answer

The speed of sound in air is 330 m s-1

The speed of sound in water is 1450 m s-1

The speed of sound in steel is 5100 m s-1

Therefore, the comparison gives —

330 : 1450 : 5100

= 33 : 145 : 510

= 1 : 4 : 15

So approximately, the speed of sound in air, water and steel are in the ratio 1 : 4 : 15
