whats 30 minutes after 9:21?

Answer 1

Its 9:51.
If 9:21 + something like 50 is given, then 21 + 50 will be obviouly greater than 60, so we have 10:11(ie., 60 + 11 = 21 + 50 = 71) hehe instead of 9:51.
I think thats what you were tryin to ask.
If not then I apologize for being oversmart. But hey, its a disease.
Cant help it.

Peace out.

Answer 2

9:51
you can solve this by adding 30 to 21 this number stays under 60 therefore you know that it's still 9 hour. if you ever have to do this again and the time goes over 60 just take the minutes it goes over and those would be part of the next hour, for example if you had to figure out what 40 minutes after 9:21 was, you just add the 40 to 21 which would give your 61 and then you would have 1 over 60 so it would be 10:01
hope this helps!

Answer 3

Let us bring the question further and change to whats 50 minutes after 9:21

Add 50 minutes to 21 to give : 71 minutes,
Since 71minutes > 60 minutes, do 71-60 = 1 hr 11 minutes

Add 1 hr to 9

Now the answer is 10 : 11

Answer 9

so if when you add up 21Min's to the 30Min's its doesn't add up to 60Min's then your answer will be 9hrs and the Min's i gonna count OK lol

9:21+0:30 ( the 0 represent no hr)
so take 21+30 which will add up to 51
so then just put the hrs together with the Min's and you'll get your answer with would be
9hrs 51Min's
9:51
