Sec Este Solution: a. The normal times are calculated as follows: Work element 1: NT, = (0.52)(1)(1.1) = 0.572 minute Work element 2: NT, -(0.24)(1)(1.2) -0.288 minute Work element 3:NT, = (0.65)(1)(1.2) = 0.780 minute Work element 4:NTA = (1.20)(1)(0.9)= 1.080 minutes Total = 2.720 minutes b. Calculating standard time: ST - NTC(1.0+A) 2.72(1.0+0.2) = 3.264 minutes Sec Este Solution: a.
