Question

In tryouts for the olympics a speed skater had times of 44,64,43,45,42,79 and 4,228 seconds find the average time add numbers

Answer 1

`Average = 43.29`

Explanation:

Given

Time: 44.64,43.45,42.79 and 42.28

Required

Determine the average time

Average or mean is calculated as thus;

`Mean = (\sum x)/(n)`

Where

`\sum x` = sum of observation

n = number of observation = 4

`Average = (44.64 + 43.45 + 42.79 + 42.28)/(4)`

`Average = (173.16)/(4)`

`Average = 43.29`

Hence, the average time is 43.29
