Total Float given Start Time Solution

STEP 0: Pre-Calculation Summary

Formula Used

Total Float = Late Start Time-Early Start Time
TF₀ = LST-EST
This formula uses 3 Variables

Variables Used

Total Float - (Measured in Second) - Total float is the period by which an activity can shift its timing without affecting the relevant schedule completion date.
Late Start Time - (Measured in Second) - Late Start Time is the latest point in time when the scheduled activity can begin so as not to delay the project completion date or any constraint.
Early Start Time - (Measured in Second) - Early Start Time is the earliest point in time when the scheduled activity can begin.

STEP 1: Convert Input(s) to Base Unit

Late Start Time: 23 Day --> 1987200 Second (Check conversion here)
Early Start Time: 19 Day --> 1641600 Second (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

TF₀ = LST-EST --> 1987200-1641600

Evaluating ... ...

TF₀ = 345600

STEP 3: Convert Result to Output's Unit

345600 Second -->4 Day (Check conversion here)

FINAL ANSWER

4 Day <-- Total Float

(Calculation completed in 00.020 seconds)
