Answers
Step-by-step explanation:
1days = 24 hours
a. 12days
= 12 days × 24 h
= 288 h
b. 8 days 16 hours
= 8days × 24 h
= 192 h
= (192+16)h
= 208h
c. 9 days 8 hours
= 9 days × 24 h
= 216 h
= (216+8) h
= 224h
d. 11 days 20 hours
= 11days × 24 h
= 264 h
= (264+20)h
= 284h
e. 2weeks 2 hours
= 14 days × 24 h
= 336 h
= (336+2)h
= 338 h
f. 15 days 16 hours
= 15 days × 24 h
= 360 h
= (360+16) h
= 376 h
1 hours = 60 minutes
a. 28 hours
= 28 h × 60 min
= 1680 min
b. 42 hours 30 minutes
= 42 h × 60 min
= 2520min
= (2520+30) min
= 2550 min
c. 50 hours 5 minutes
= 50 h × 60 min
= 3000 min
= (3000+5) min
= 3005 min
d. 14 hours 52 minutes
= 14 h × 60 min
= 840 min
= (840+52) min
= 892 min
e. 22 hours 35 min
= 22 h × 60 min
= 1320 min
= (1320+35)min
= 1355 min
f. 17 hours 17 minutes
= 17 h × 60 min
= 1020 min
= (1020+17) min
= 1037 min
1 minutes = 60 seconds
a. 34 minutes
= 34 min × 60 sec
= 2040 sec
b. 17 minutes 36 seconds
= 17 min × 60 sec
= 1020 sec
= (1020+36) sec
= 1056 sec
