Which of the following best represents the average rate at which a person can quickly walk?
3 steps per hour
3 steps per second
30 steps per minute
30 steps per second
I mean this one is pretty easy, eliminate the absurd ones like 30 steps per second and 3 steps per hour. if you're still having difficulty after that just walk around the room *briskly* for a minute and see whether your step count is closer to 30 (choice 3) or 180 (choice 2)
