Janez did squats for the morning workout. He made 6 of them on the first day, and then two more each day than the day before. He increased the number of squats to the number 60, and then did 60 each day.
Calculate which day John did 60 squats for the first time.
Calculate how many squats John did in the first 40 days.
John spent 2 seconds for each squat. Was a minute and a half enough for all the squats on the 20th day? The answer is computationally justified.
