If I have to do five things I start and 17 days to do it if thing one takes me 2 days exactly and the rest of the time is spread evenly how much time do I have for each of the other tasks
If there are 17 days in total and thing one takes 2 days exactly, then there are 17 - 2 = <<17-2=15>>15 days remaining for the other tasks.
Since the remaining time is spread evenly among the other tasks, each task will have 15 / 4 = <<15/4=3.75>>3.75 days.
