Express the MTM$-1$ motion elements in problem$-2$ as one or more activity sequence

models with index numbers $($a$)$ determine the normal times in TMUs for these activity

sequence models. $($b$)$ what is the total time for this$($these$)$ activity sequence model$($s$)$ in

seconds? $($c$)$ How do the MOST normal times compare with the normal times from

MTM$-1?$
