  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.
