Question

What time will be 2 hours 50 minutes after 9 : 10 a.m.?

Answer 1

Hint: In this particular question that after 12 : 00 o’clock a.m. will change into p.m. and in 1 hour there is 60 minutes, and use the concept that in a : b, a represents the hour number and b represents the minute number, so use these concepts to reach the solution of the question.

Complete step-by-step answer:
Given time:
9 : 10 a.m.
Now we have to find out what time will be 2 hours 50 minutes after 9 : 10 a.m.?
As we all know that in 1 hour there is 60 minutes.
And we all know that in a : b, a represents the hour number and b represents the minute number.
So add 2 hour in 9 hour and add 50 minutes in 10 minutes, we have,
Therefore, (9 + 2) : (10 + 50) = 11 : 60 a.m.
Now 60 minute = 1 hour.
So 11 changed into 12 and 60 changed into 00.
So the actual time is (11 + 1) : (60 - 60) = 12 : 00
As we all know if we start from a.m. then at 12 o’clock it will remain a.m. and past 12 o’clock it will convert into p.m.
But if we start from p.m. then at 12 o’clock it will remain p.m. and past 12 o’clock it will convert into a.m.
So, 9 : 10 a.m. + 2 hours 50 minutes = 12 : 00 a.m.

So this is the required answer.

Note: Whenever we face such types of questions the key concept we have to remember is that in 60 minutes there is 1 hour, so if in a:b, if b is greater than or equal to 60 than a is convert in to (a + 1) and b is convert into (b - 60) so the actual time become (a + 1) : ( b – 60), and always recall that if we start from a.m. than at 12 o’clock it will remain a.m. and past 12 o’clock it will convert into p.m. and if we start from p.m. than at 12 o’clock it will remain p.m. and past 12 o’clock it will convert into a.m.
