Let's say that I found a slightly different answer. Because June 1st is a Sunday I found that the expected time to complete is 28 days. Thus, I only need to shorten the path by three days. Technically, could I "crash" any of the four activities on the critical path? Tasks B,D,E and H are all less than three days. B=7 days, D=8 days, E=8 days, H=6 days
