What is 4 hours and 76 mins - 2hrs and49 mins

First, lets convert both values to minutes only ...

1hr=60min

4 hours and 76 minutes:

4hr+76min=

4*60+76=

240+76=316minutes

2hours and 49minutes:

2hr+49min=

2*60+49=

120+49=169minutes

Now we can solve the problem ...

316minutes-169minutes=147minutes

Answer=147 minutes

If you want to convert 147 minutes to hours and minutes ...

1min=1/60hr

147min*1/60 = 2hours and 27 minutes

The answer would be 147
