Question

If it's 9:38 am what time will it be if i add 30 minutes to it

Answer 1

It will be 10:08am Got it now

Answer 2

9:68

But that wouldn't make sense, so you do 68-60=8

Therefore, that would add another hour.

10:?

The extra 8 that you subtracted would be the minutes.

10:08 would be the answer. 

Hope it helps!
