Xuan usually takes a bus from her home to school. If she leaves home at 06 00, she will reach school at 07 54. 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 9 min.
- How long does Xuan take to go school by the new MRT line?
- Xuan spent the next 7 h 15 min in school before dismissal. If Xuan started school at 08 55, at what time was she dismissed from school? Give your answer in the 12-hour clock format.
(a)
From 06 00 to 07 54: 1 h 54 min
Duration of Xuan's journey to go to school by the new MRT line
= 1 h 54 min - 9 min
= 114 min - 9 min
= 105 min
= 1 h 45 min
(b)
7 h 15 min after 08 55 = 16 10
16 10 = 4.10 p.m.
Time that Xuan was dismissed from school: 4.10 p.m.
Answer(s): (a) 1 h 45 min; (b) 4.10 p.m.
