Ivory usually takes a bus from her home to school. If she leaves home at 05 00, she will reach school at 06 48. Last week, a new MRT line has opened and she can take the train directly from home to school instead. This will shorten her journey by 2 min.
- How long does Ivory take to go school by the new MRT line?
- Ivory spent the next 3 h 45 min in school before dismissal. If Ivory started school at 09 25, at what time was she dismissed from school? Give your answer in the 12-hour clock format.
(a)
From 05 00 to 06 48: 1 h 48 min
Duration of Ivory's journey to go to school by the new MRT line
= 1 h 48 min - 2 min
= 108 min - 2 min
= 106 min
= 1 h 46 min
(b)
3 h 45 min after 09 25 = 13 10
13 10 = 1.10 p.m.
Time that Ivory was dismissed from school: 1.10 p.m.
Answer(s): (a) 1 h 46 min; (b) 1.10 p.m.
