Answer:
SPEED=DISTANCE/TIME. To work out the speed of the sound in metres per second, divide the distance in metres by the average time in seconds. For example 170 metres divided by 0.50 seconds = 340 m/s. You have calculated the speed of sound!

Explanation:
To calculate the standard deviation for a sample of N measurements:
Sum all the measurements and divide by N to get the average, or mean.
Now, subtract this average from each of the N measurements to obtain N "deviations".
Square each of these N deviations and add them all up.
Divide this result by. (N − 1)
