Personal Advantage

.858

Convert to distance the sound traveled into miles and average time in hours.

Time: .858= .00023 (.693) =.000019

Distance: 100 yards=300feet=0.018

Measure speed

.018/.00023hrs=78.26 mi/hour

Compare measured value

Speed of sound: 767 mi/hour

The speed of sound is faster than light. All the numbers where different, which meant that the distance changed when divided by your own hours and the average mph. Miles over time will equal mph 947mi/hour. We went out side and calculated how long it would take to hear the sound of two boards being hit together.

We put water in a tube then we hit a tuning fork with mallet and then put on top of a poll to see where the highest noise would start with the poll going deeper in the water or out of the water closer to the top.

       Dominoes

When the dominoes where hit over, the line with the dominoes farther away from each other went down slower than the ones with the dominoes where closer together. 

Air travels faster than Gas, liquid, or a solid because there is less blockage
