step by step explain
Answers
Step-by-step explanation:
1. Add 3 hr. 25 min. 15 sec. and 5 hr. 20 min. 25 sec.
Adding Time
We added hours, minutes and seconds respectively.
2. Add 5 hr. 45 min. 12 sec. and 7 hr. 50 min. 24 sec.
Addition of Hours, Minutes and Seconds
= 12 hr. 1 hr. + 35 min. + 36 sec.
= 13 hr. 35 min. 36 sec.
12 hr. 95 min. 36 sec.
= 12 hr. + (60 min. + 35 min.) + 36 sec.
= 12 hr. 1 hr. + 35 min. + 36 sec.
= 13 hr. 35 min. 36 sec.
3. Add 30 hr. 45 min. 45 sec. and 15 hr. 35 min. 17 sec.
Addition of Hours
= 45 hr. 1 hr. 20 min. 1 min. 11 sec.
= 46 hr. 21 min. 11 sec.
45 hr. 80 min. 71 sec.
= 45 hr. + (60 min. + 20 min.) + (60 sec. + 11 sec.)
= 45 hr. + 1 hr. + 20 min. + 1 min. + 11 sec.
= 46 hr. 21 min. 11 sec.
4. Add 24 hr. 30 min. 20 sec. and 18 hr. 37 min. 54 sec.
Addition of Hours and Minutes
= 42 hr. 1 hr. 7 min. 1 min. 14 sec.
= 43 hr. 8 min. 14 sec.
42 hr. 67 min. 74 sec.
= 42 hr. + (60 min. + 7 min.) + (60 sec. + 14 sec.)
= 42 hr. + 1 hr. + 7 min. + 1 min. + 11 sec. + 14 sec.
= 43 hr. 8 min. 14 sec.
