You need to get to class, 200 meters away, and you can only walk in the hallways at about 1.5 m/s. (if you run any faster, you’ll be caught for running). How much time will it take to get to your class?
200/1.5 = 133.33 seconds. = approximately 2 mins and 13 secs.
Time = distance / velocity = 200/1.5 = 133.3333 s. Thus, the time will be around 133 seconds or 2 minutes 13 seconds.
