The correct option is D 5:15 p.m;, 7:30 a.m.; 3:15 p.m.; 192 hours; 28 days
We can use the following terminology:
=> Quarter past means 15 minutes later.
=> Quarter to means 15 minutes before.
=> Half past means 30 minutes later.
Therefore,
a. Quarter past 5:00 p.m. = 15 minutes later = 5:15 p.m.
b. Half past 7:00 a.m. = 30 minutes later = 7:30 a.m.
c. Quarter to 3:30 p.m. = 15 min before = 3:15 p.m.
Now, we know that,
1 day = 24 hours 1 week = 7 days
d. 8 days = 8 × 24 = 192 hours
e. 4 weeks = 4 × 7 = 28 days
