Could someone please help me with this. I understand that you crash activity 5-6 first (to get to 12 days) and then 4-5 second (to get to 11 days). But then wouldn't there would be two critical paths: 1-4-6 and 1-4-5-6. So I'm not sure how to keep crashing it to get to a minimum. If you could also provide an explanation that would be great, I'm so confused. Thanks
