completion time and the critical path should also be determined. Here are the activity times:

$\backslash$table$[[$Activity$,$Time $($weeks$),$Immediate Predecessor$($s$),$Activity,Time $($weeks$),$Immediate Predecessor$($s$)],[$A$,7,-,$E$,5,$B$,,,,,,],[$B$,8,-,$F$,6,$B$,,,,,,],[$C$,4,$A$,$G$,11,$C$,$ E$,,,,,,],[$D$,1,$A$,$H$,7,$D$,$ F$,,,,,,]]$

Dave's earliest start $($ES$)$ and earliest finish $($EF$)$ are:

$\backslash$table$[[$Activity$,$ES$,$EF$],[$A$,0,7],[$B$,0,8],[$C$,7,11],[$D$,7,8],[$E$,8,13],[$F$,8,14],[$G$,13\sqrt[\phantom{2}]{?},24],[$H$,14,21]]$

Dave's latest start $($LS$)$ and latest finish $($LF$)$ are:
