A wooden plank of length x is cut into 8 sections such that
each section is at most 2 1/2 meters long. What is the
length of the entire plank in meters?

The length of the entire plank is B. .

Step-by-step explanation:

Step 1:

It is given that each section is at most meters long. The entire length, x of the plank is cut into 8 such sections.

So to calculate the length of x, we use the following formula,

The length of the entire plank = 8 (the length of each section).

By converting into decimals, we get each section is 2.5 meters long.

Step 2:

The length of the entire plank = meters.

In the question, it is given that each section is at most 2.5 meters long meaning the length can be 2.5 meters or lesser but cannot be higher.

So the entire length can be 20 meters or lesser but cannot be any higher.

So option B.   is the length of the entire plank in meters.
