Question

What is the elapsed time between 8:00 a.m and noon ?

Answer 1

Four Hours

Explanation:

Noon is equivalent to 12:00pm

This is how I would usually do that in my head and counting on my fingers:

8am to 9am is one hour.

9am to 10 am is one hour.

10am to 11am is one hour.

11am to 12pm is one hour.

Add those hours together and you get four hours.

Alternatively, 12-8=4 so four hours.

Answer 2

4 hours because noon is 12. 8-12 is 4
