Answer 1

The answer to the question above is 13:30

Answer 2

Answer: 14:30

Step-by-step explanation:

19:13 - 4.43 looks easy, but time expressed in 24-hour format is a base 60 calculation in the decimal portion.  It only contains values between 0 and 59.

I broke it it down to simplify:

1)  Take 13 minutes off the 19:13 to make it 19:00.  

2)  Then take the same 13 minutes off the 4.43, which would make it 4.30 (4 1/2 hours)

3)  Now take off the 4.30 from the 19:00.  The 4 portion of 4.3 can be removed:  19:00 - 4:00 = 15:00.  Then remove the 0:30 portion (1/2 hour), which would leave 14:30.

14:30 plus 4:43 = 18:73, but the 0:73 must convert to 1:13 to account for the 60 minutes/hour format
