Answer:
a.3 hour 10 mins
b.3 hours 13 mins 20 sec
c.2 hours 44 mins
d.2hour 25 mins and 44 sec
Step-by-step explanation:
1 hour = 60 minutes
A. 19 - 16 = 3 (hours)
35 - 25 =10 (minutes)
Answer = 3 hours 10 minutes
B.10 -7= 3 (hours)
25 - 12=13 (minutes)
40 - 20 = 20 (seconds)
Answer = 3 hour 13 minutes 20 seconds
C. This is Tricky right.
40-56=-16 (minutes)
15 hours - 12 hours = 3 hours
1 hour = 60 minutes
3 hours = 180 minutes Right.
180-16 =164 (minutes)
If we transform it back to hours then :
164 minutes = 2 hours
and 44 minutes left so thats the answer.
Answer = 2 hour 44 minutes
D.
15 -12= 3 (hours)
3 hours = 180 minutes
180 -35= 145
145 minutes = 2 hours and 25 minutes
Now for Seconds
Take 1 minute from 25 minutes
25-1= 24 (minutes)
1 minute = 60 seconds
60 -16 =44 (seconds)
Thats the answer!
Answer= 2 hour 25 minutes 44 seconds.
