Answer:
Let add and subtract:
1 hr = 60 minutes
1 min = 60 secs
Hence the number of second in 1 hr is,
1 hr = 60 60 = 3600 sec
a)(4hr 33min 20sec)+(9hr 52min 25sec) = 13hr 85 min 45sec
= 14 hr 25 min 45 sec
b)(6hr42min2sec)-(2hr 55min 42sec) = 3 hr 46 min 20 sec
c)(18r 19min 15sec)+(9hr 55min 48sec) = 27 hr 74 min 63 sec
= 28 hr 75 min 3 se
d)(23hr 7min)-(19hr 29min 18sec) = 3 hr 37 min 42 sec
These are the answers of the given questions.
