Suppose we have the following project digraph. $($The numbers in parenthesis represent hours.$)$

$$

Assume that this project is scheduled using two processors, and the decreasing time algorithm.

Use this information to fill in the blanks and answer the following questions.

$($For parts a$,$ c and d enter only a number. For part b$,$ enter only a letter. For part $e,$ answer "yes" or $"$no$")$

a$)$ The critical time for this project is: $$ hours.

b$)$ What will be the first task assigned to Processor $1?$

c$)$ At what time will time will task $F$ be started? $t=$

d$)$ What is the completion time for the project with this schedule?

Completion Time $=$ hours
