No prob.

saifoo.khan · Answer

10:20 + 3 = 13:20

or in other words,

1:20pm.

anonymous · Answer

So, my 6:30pm is wrong,lol

anonymous · Answer

I'm not sure what the 13:20 means

saifoo.khan · Answer

1320 hrs (in 24 hours clock)

anonymous · Answer

ha oh, but where are you getting the 3?

anonymous · Answer

it's 10 difference right?

saifoo.khan · Answer

How i got 3?

Answer = 30/60 * 90 = 45

45/10 = 4.5hrs
          = 4 hrs and 30mins

therefore,
10:20 + 4:30

02:50 pm.
