Hi

When you find 23h50, it means 23.5 hours.

0.5 hours is 30 minutes !

Therefore it is 23h 30'

And your answer was right

Hope it helped

Bye !

That's because there are 60 minutes in an hour, not 100. So 23.5 hours, or rather 23 1/2 hours is the correct "fraction of hours".

Separate the whole number of hours from the fractional (or decimal) part of the hours, and multiply that fractional part by 60. That gives you the number of minutes. For example, 15.25 hours is 15 hours plus 0.25 hours, or 15 hours and 0.25*60= 15 minutes.
