An archery range calculated the average speed of wooden arrows shot during a competition. Which is the best representation of the average speed?

To find an average, add all the speeds of each arrow together and divide that number by the total number of arrows shot.

example:

Arrow 1:

20mph

Arrow 2:

23 mph

Arrow 3:

23 mph

= 20+23+23 = 66

66: 3 = 22 mph on average
