Question

Akeem will record the time it takes him to run 1 mile each day for 7 days. In order to meet his fitness challenge, his mean running time for 7 days must be 9 minutes or less. A list of Akeem's running times, in minutes, for the first 6 days is shown.

9.4, 9.0, 9.1, 8.9, 8.5, 8.8

Answer 1

The time Akeem runs on days must be 9.3 minutes or less than 9.3 minutes if the mean running time for 7 days must be 9 minutes or less.

What is mean?

It is defined as the single number that represents the mean value for the given set of data or the closed value for each entry given in the set of data.

We have:

Akeem will record the time it takes him to run 1 mile each day for 7 days. In order to meet his fitness challenge, his mean running time for 7 days must be 9 minutes or less.

Here we are assuming that it is required to find the time Akeem runs on the 7th day.

Let's suppose Akeem runs x minutes on the 7th day.

Mean running time ≤ 9

The mean:

$\dfrac{(9.4+9.0+9.1+8.9+8.5+8.8+x)}{7} \leq 9$

$\dfrac{(53.7+x)}{7} \leq 9$

53.7 + x ≤ 63

x ≤ 9.3 minutes

Thus, the time Akeem runs on days must be 9.3 minutes or less than 9.3 minutes if the mean running time for 7 days must be 9 minutes or less.
