Dear, sir If I'm asked to check the result of an experiment every four hours, And if I checked it first at 3pm, should I check it again at 7pm or 6pm. I thought it was a very simple question, but a book is confusing me.
Top answer
Check it at 7 pm. There are 24 hours in a day; every 4 hours is 6 times a day-- midnight, 4 am, 8 am, noon, 4 pm, 8 pm.
