Total Float given Start Time Solution

Follow our step by step solution on how to calculate Total Float given Start Time?

FIRST Step Consider the formula

TF 0 = LST - EST

Next Step Substitute values of Variables

∴

TF 0 = 23d - 19d

Next Step Convert Units

∴

TF 0 = 2E+6s - 1.6E+6s

Next Step Prepare to Evaluate

∴

TF 0 = 2E+6 - 1.6E+6

Next Step Evaluate

∴

TF 0 = 345600s

LAST Step Convert to Output's Unit

∴

TF 0 = 4d
