Answer 2

To subtract the two given time intervals, we need to perform subtraction separately for hours and minutes.

Hours: 4 hours - 3 hours = 1 hour

Minutes: 10 minutes - 50 minutes = -40 minutes

Since the result of the minutes subtraction is negative, we need to borrow 1 hour from the hours result.

1 hour - 1 hour = 0 hours

Now we have 0 hours and -40 minutes. To convert the negative minutes to positive, we can add 60 minutes.

0 hours + 1 hour = 1 hour -40 minutes + 60 minutes = 20 minutes

Therefore, 4 hours 10 minutes - 3 hours 50 minutes is equal to 1 hour 20 minutes.
