Question

suppose you made 5 measures of your walking time and got the following values: 5.6 s, 5.9 s, 5.5 s, 5.6 s, and 5.8 s what is the average walking time (in seconds)? add your answer integer, decimal, or e notation allowed

Explanation:

Step1: Sum the walking times

To find the average, we first sum all the values. The values are \( 5.6 \, \text{s} \), \( 5.9 \, \text{s} \), \( 5.5 \, \text{s} \), \( 5.6 \, \text{s} \), and \( 5.8 \, \text{s} \). So the sum \( S = 5.6 + 5.9 + 5.5 + 5.6 + 5.8 \). Calculating this: \( 5.6 + 5.9 = 11.5 \), \( 11.5 + 5.5 = 17 \), \( 17 + 5.6 = 22.6 \), \( 22.6 + 5.8 = 28.4 \). So \( S = 28.4 \, \text{s} \).

Step2: Divide by the number of measures

There are 5 measures. The average \( \bar{x} = \frac{S}{n} \), where \( n = 5 \). So \( \bar{x} = \frac{28.4}{5} \). Calculating this division: \( 28.4 \div 5 = 5.68 \).

Answer:

\( 5.68 \)
