Question

Sound takes 2 seconds to travel 3 kilometres in water. What is the speed of sound in water?​

Answer 1

the speed of sound in is distance/ time

= 3000metre / 2

=1500 m / sec.

Answer 2

The speed of sound in the water is 5400 km/h.

• Given data :

The sound travels 3 kilometres in 2 seconds in the water medium.

• Now, we will calculate the speed of the sound in the water medium,in the kilometres per hour unit because kilometres per hour unit is the most common unit of the speed measurement.

• We know that,

1 hour = 3600 seconds

• The sound travels in :

2 seconds = 3 kilometres

1 second = 3/2 kilometre

3600 seconds = (3×3600)/2 = 5400 kilometres

So,the speed of the sound in the water medium is 5400 kilometres per hour. (Answer)
