Answer:

the length of the entire plank is less or equal to 20 meters

Step-by-step explanation:

when the wooden plank is divided into 8 sections, the length of each section is 5/2 meters or less. Since we don't know exactly what is the length of every part, we just can calculate the maximum value of the wooden plank.

The maximum length of the entire plank is given by the next equation:

X maximum= (# sections)*(length maximum of every section)

X maximum= 8 * 5/2 meters

X maximum = 20 meters

This result says that X is less or equal to 20 meters.
