A recently negotiated union contract allows workers in a shipping department 24 minutes for rest, 10 minutes for personal time,

Alik [6]

Answer:7.125 min

Step-by-step explanation:

Given

Resting time =24 min

Personal time=10 min

Delay=14 min

Observed Time=6min/cycle

Performance Rating=95%

Allowance Time=Rest time+Personal time+delay

Allowance time=24+10+14=48 min

$Allowance %=\frac{Allowance Time}{Total Time}=\frac{48}{4\times 60}=20 \%$

Allowance Factor= $\frac{1}{1-0.20}=\frac{5}{4}$

Calculate the Normal Time

Normal time=Observed time $\times$ personal Time=6\times 0.95=5.7 min

Standard time=Normal time $\times$ Allowance Factor

Standard time = $NT\times Allowance factor=5.7\times 1.25$ =7.125 min
