Question

If I sleep 6 hours a day for 2 day how many hours did I sleep

Answer 1

If you sleep for 6 hours a day, then for 2 days, you sleep for 12 hours because 2 * 6 = 12.

Answer 2

if you sleep 6 hours each day and you do this 2 days, all you would have to do is multiply the two numbers together to get your answer. Therefore your answer is 12 hours a day.
