Free Float Solution

STEP 0: Pre-Calculation Summary

Formula Used

Free Float = Early Finish Time-Early Start Time-Activity Time
FF₀ = EFT-EST-t_activity
This formula uses 4 Variables

Variables Used

Free Float - (Measured in Second) - Free Float is the period by which an activity can shift in its timing without affecting the Early Start of any succeeding activity or event.
Early Finish Time - (Measured in Second) - Early Finish Time is the earliest point in time when the scheduled activity can complete.
Early Start Time - (Measured in Second) - Early Start Time is the earliest point in time when the scheduled activity can begin.
Activity Time - (Measured in Second) - Activity time is the estimated task duration based on preceding logic and constraints.

STEP 1: Convert Input(s) to Base Unit

Early Finish Time: 46 Day --> 3974400 Second (Check conversion here)
Early Start Time: 19 Day --> 1641600 Second (Check conversion here)
Activity Time: 20 Day --> 1728000 Second (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

FF₀ = EFT-EST-t_activity --> 3974400-1641600-1728000

Evaluating ... ...

FF₀ = 604800

STEP 3: Convert Result to Output's Unit

604800 Second -->7 Day (Check conversion here)

FINAL ANSWER

7 Day <-- Free Float
