To calculate the efficiency of the assembly line, use the formula: Efficiency = (Total Task Time / (Number of Workstations * Cycle Time)) * 100. Assuming the total task time remains constant, and given the desired output rate of 120 units per hour, the cycle time is 60/120 = 0.5 minutes per unit. With four workstations, the efficiency falls between 85% and 90%.
