A student measures the speed of sound. He claps his hands and the sound reflects from a wall which is 100m away from him.
An electronic timer detects the echo of the sound 0.60s after it is made.
Which calculation should the student use to determine the speed of sound?
1 )
${{100} \over {0.60}}m/s$
2 )
${{100} \over {1.2}}m/s$
3 )
${{200} \over {0.30}}m/s$
${{200} \over {0.60}}m/s$
