Shiyun usually takes a bus from her home to school. If she leaves home at 07 00, she will reach school at 08 30. 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 4 min.
- How long does Shiyun take to go school by the new MRT line?
- Shiyun spent the next 6 h 55 min in school before dismissal. If Shiyun started school at 09 45, at what time was she dismissed from school? Give your answer in the 12-hour clock format.
(a)
From 07 00 to 08 30: 1 h 30 min
Duration of Shiyun's journey to go to school by the new MRT line
= 1 h 30 min - 4 min
= 90 min - 4 min
= 86 min
= 1 h 26 min
(b)
6 h 55 min after 09 45 = 16 40
16 40 = 4.40 p.m.
Time that Shiyun was dismissed from school: 4.40 p.m.
Answer(s): (a) 1 h 26 min; (b) 4.40 p.m.
