Answer 2

Answer:

Option A - 25.2 seconds

Step-by-step explanation:

Given : Your friend swims on the school team. In her first four races, her times are 26.3, 28.4, 25.6, and 29.1 seconds.

To find : Which time listed for her next race would make the range larger?

Solution :

The range is the difference between the highest and lowest value.

In the given values , 26.3, 28.4, 25.6, and 29.1

Lowest value is 25.6

Highest value is 29.1

To make a larger range,

We simply need to pick a number smaller than 25.6 or larger than 29.1.

This will produce a larger difference (or range).

In the given options,

A. 25.2<25.6 seconds

B. 26.1>25.6 seconds

C. 28.0>25.6 seconds

D. 29.1=29.1>25.6 seconds

Only option A satisfy the condition.

Therefore, Time for her next race would make the range larger is 25.2 second.
