Given the project within the table below, calculate the following:

ActivityPredecessorTime (days)A--7.5B--9.7C--10.5DA, C8.8ED10FB, E4.2GF9.7HG11.5

a. What is the project length? [ Select ] ["54.7 days", "48.3 days", "52.5 days", "51.7 days", "47.8 days"]

b. What activities are on the critical path? [ Select ] ["B, F, G, H", "C, D, E, F, G, H", "A, C, D, E, F, G, H", "A, B, C, D, E, F, G H", "A, D, E, F, G, H"]

c. How much slack is in activity A? [ Select ] ["0 - it is on the critical path", "7.5 days", "3.0 days", "19.6 days", "5.0 days"] , and activity B? [ Select ] ["11.4 days", "22.6 days", "6.7 days", "0 days", "19.6 days"]

d. What is the Late Start / Late Finish for activity B? [ Select ] ["16.5 and 27.8", "22.6 and 26.3", "19.6 and 29.3", "16.3 and 26.3", "0 and 9.7"]

e. What would happen to the overall project length if activity E was delayed by 4 days, now taking a total of 14 days? [ Select ] ["the project length will now be 58.7 days", "the project length would remain the same, but c would now be on the critical path", "the project length will now be 53.7 days", "the project time would be reduced by 4 days because of E having 4 days of slack", "the project length would remain the same"]
