Firstly, we convert the hour into minutes

As we know that 1hr=60min

Therefore 7hr 25min=(7*60)+25=445min

3hr 45min=(3*60)+45=225 min

Now, subtracting 225min from 445min

445-225=220min

which is equal to( 3*60)+40= 3hr 40min

To find the difference between 7 hours 25 minutes and 3 hours 45 minutes, we can subtract the hours and minutes separately.

Hours difference: 7 hours – 3 hours = 4 hours

Minutes difference: 25 minutes – 45 minutes = -20 minutes

Since the minutes difference is negative, we need to borrow 1 hour from the hours difference.

4 hours – 1 hour = 3 hours

Now, we add the remaining minutes to the borrowed hour:

-20 minutes + 60 minutes = 40 minutes

So, the correct difference between 7 hours 25 minutes and 3 hours 45 minutes is 3 hours and 40 minutes.
