Free PMI Project Management Professional Practice Question

The correct answer is 3 days. Float, also known as slack, is the amount of time an activity can be delayed without affecting the project's overall schedule. It can be calculated using two formulas:

1. Float = Late Start (LS) - Early Start (ES)
2. Float = Late Finish (LF) - Early Finish (EF)

In this question, we are given the Early Start (ES) and Late Start (LS) values. Using the first formula:

Float = LS - ES Float = 8 - 5 Float = 3 days

This means the activity can be delayed by up to 3 days without impacting the project's completion date. Understanding float is crucial for project managers as it helps in prioritizing tasks, managing resources, and identifying potential schedule risks.
