Subtraction of Hours, Minutes and Seconds
We will discuss here about the subtraction of hours, minutes and seconds.
Let us consider some of the examples on subtracting time.
1. Subtract 24 hr. 15 min. 38 sec. from 45 hr. 20 min. 54 sec.
 |
We subtract hours, minutes and seconds respectively. |
2. Subtract 5 hr. 16 min. 48 sec. from 12 hr. 28 min. 16 sec.
 |
16 sec. < 48 sec. So, we borrow 1 min. = 60 sec. From 28 min.
60 sec. + 16 sec. = 76 sec. 76 sec. – 48 sec. = 28 sec. |
3. Subtract 14 hr. 46 min. 32 sec. from 22 hr. 28 min. 17 sec.
 |
17 sec. < 32 sec. So, we borrow 1 min.
= 60 sec. from 28 min. 60 sec. + 17 sec. = 77 sec. 77 sec. – 32 sec. = 45 sec. 27 min < 46. So we borrow 1 hr. = 60 min . from 22 hr. 60 min. + 27 min. = 87 min. 87 min – 46 min. = 41 min. |
4. Subtract 20 hr. 52 min. 46 sec. from 40 hr. 19 min. 20 sec.
 |
20 sec. < 46 sec. So, we borrow 1 min.
= 60 sec. from 19 min. 60 sec. + 20 sec. = 80 sec. 80 sec. - 46 sec. = 36 sec. 18 min < 52 min. So we borrow 1 hr. = 60 min . from 40 hr. 60 min. + 18 min. = 78 min. 78 min - 52 min. = 26 min. |
