Question

Aditi claps and hear the echo after reflection from a cliff which is 990m away. If the velocity of sound is 330 m/s, calculate the time taken for hearing the echo.

Answer 1

Answer:

Distance = 990 m

Speed = 330 m/sec.

So, time=distance/speed

=(990/330)m/sec.

=3 m/sec.

Hence,ans.=3m/sec

Explanation:

Answer 2

Answer:

The Answer is 3m/s.

Explanation:

Speed × Time= Distance

Therefore, Time = Distance

Speed

Distance Given: 990m

Speed Given: 330m/s

Therefore, Time= 990

330

= 3m/s

I hope you are now clear about the Ans.
