would be then 0 for the Total Float and the the Free Float for A.

Activity B would be the same thing Total Float under Free float 0.

D and G will have the same Total Float and the Free Float equal 0.

If you would follow the equations of the Total Flow, that's simply state forward.

The Free Float also, you always look at the minimum start dates for

the critical activities, and this is a good example for activity B here.

It highlighted that the early start for the successors, it happened to become

also the same end start of 11, and the same for D as well.

Now let's look at activity E and compare it with your solution here.

The total float of activity E would be 14- 16 or 19- 16,

which is 3.

And the minimum of early start of the successor of activity E,

which will be 19 minus the early finish of activity E of 16,

that will give us also 3.

And for activity C here,

the total float will be 9- 4, 5.

And the free float of activity C, will be the minimum

between the early start of the successors, E and F.

The early start of E 11, the early start of F 9.

So we'll take the 9 minus the early finish of C which is 9 which is equal zero.
