Dr. Johnson told his son that he would pay him $6.00 per hour for the 6 seconds it took his son to wash his hands before dinner.
How much money will Dr. Johnson’s son receive?

[su_spoiler title=”See the answer” style=”fancy”]
1 cent.
1 hour=60 mins x 60 secs=3600 seconds. So if Dr. Johnson pays $6.00=600 cents per 3600 seconds, then for 6 seconds he will pay (600/3600) x 6 = 1 cent.
