Question

Jaiden ran a 100 yard dash three times and took the average of his times. His times were 12.7, 11.2 and 11.8 seconds. On average, how long does it take him to run a 100 yard dash?

Answer 1

Using the mean concept, it is found that on average, it takes him 11.9 seconds to run a 100 yard dash.

What is the mean?

The mean of a data-set is given by the sum of all observations in the data-set divided by the number of observations.

In this problem, the three observations are given by:

12.7 s, 11.2 s, 11.8 s.

Hence the mean is:

M = (12.7 + 11.2 + 11.8)/3 = 11.9.

On average, it takes him 11.9 seconds to run a 100 yard dash.
