Ivory usually takes a bus from her home to school. If she leaves home at 05 00, she will reach school at 06 49. 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 20 min.
- How long does Ivory take to go school by the new MRT line?
- Ivory spent the next 3 h 30 min in school before dismissal. If Ivory started school at 08 30, at what time was she dismissed from school? Give your answer in the 12-hour clock format.
(a)
From 05 00 to 06 49: 1 h 49 min
Duration of Ivory's journey to go to school by the new MRT line
= 1 h 49 min - 20 min
= 109 min - 20 min
= 89 min
= 1 h 29 min
(b)
3 h 30 min after 08 30 = 12 00
12 00 = 12.00 p.m.
Time that Ivory was dismissed from school: 12.00 p.m.
Answer(s): (a) 1 h 29 min; (b) 12.00 p.m.
