Answer: Greater than 12% but less than 18%.
Step-by-step explanation:
Total productive time, p is given as:
= 300 seconds
Cycle time, c = 90 seconds
The number of workstations, n is given as = 4
The formula to solve this will be:
= [p/(n x c)] x 100
= [300/(4 x 90)] x 100
=[(300/360) x 100
= 0.83 × 100
Line efficiency = 83.33%
Since the line efficiency has been gotten, we then calculate the balance delay which will be:
Balance delay = 100 - Line efficiency
= 100% - 83.33%
= 16.67%
The answer then will be Greater than 12% but less than 18%.
