Calculating speed of sound

Using our timings can you calculate the speed of ‘our’ sound.

‘Our sound’ travelled the 100m from the wooden blocks to our ears in 1.12 seconds.

We worked out that it would have taken 11.2 seconds to travel 1000m.

What is the speed of ‘our sound’ in metres/second?

Can you convert this into kilometers per hour?

How does this compare to the actual speed of sound which is 1236 kilometers per hour?

 

What does this tell you about the accuracy of our investigation?
