✅ Answer: 5 minutes

Each machine makes 1 widget in 5 minutes. That rate doesn’t change when you add more machines.

5 machines → 5 widgets in 5 minutes (1 widget per machine)

100 machines → 100 widgets in 5 minutes (still 1 widget per machine)

The number of machines and widgets scaled equally. The time stayed the same. Your brain saw “5, 5, 5” then “100, 100” and wanted to complete the pattern with “100.” That’s called anchoring bias.

Score: __/2
