Question

What is the change of time between 2.15, 2.05, 2.02

Answer 1

Average = 2.073

Explanation:

Given:

Time: 2.15, 2.05, 2.02

Required

Determine the average

Average is calculated as thus:

Average = \frac{\sum x}{n}

In this case:

\sum x = 2.15+2.05+2.02

and

n = 3

Average = \frac{\sum x}{n} becomes

Average = \frac{2.15+2.05+2.02}{3}

Average = \frac{6.22}{3}

Average = 2.073
