The way I worked out the number of weeks is74166 / 200 (best case lines of code per hour, based on last slide) = 370.83Took that divided by 8 (best case number of hours a day) = 46.35Then took that divided by 6 (worst case number of hours a day) = 61.8And then got the average = 54.07Note this is a human year… could add more developers to it
