Answer :
- Time is 4 seconds
Given :
- A boy standing 660m away from sources of sound heats it after some time
- Speed of sound is 330m/s
To find :
- Calculate the time after which the boy hears the sound
Solution :
Given,
- Distance (d) = 660m
- Speed of sound (v) = 330m/s
As we know that,
- Distance = Speed × Time
Here , sounds travels twice time, First sound travel to the cliff then from the cliff to the boy
⇢ Distance = Speed × Time
⇢ 660m × 2 = 330m/s × time
⇢ time = 660m × 2 / 330m/s
⇢ time = 2 × 2s
⇢ time = 4 seconds
Hence , Time is 4 seconds.
