Yen usually takes a bus from her home to school. If she leaves home at 08 00, she will reach school at 09 42. 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 16 min.
- How long does Yen take to go school by the new MRT line?
- Yen spent the next 4 h 40 min in school before dismissal. If Yen started school at 09 30, at what time was she dismissed from school? Give your answer in the 12-hour clock format.
(a)
From 08 00 to 09 42: 1 h 42 min
Duration of Yen's journey to go to school by the new MRT line
= 1 h 42 min - 16 min
= 102 min - 16 min
= 86 min
= 1 h 26 min
(b)
4 h 40 min after 09 30 = 14 10
14 10 = 2.10 p.m.
Time that Yen was dismissed from school: 2.10 p.m.
Answer(s): (a) 1 h 26 min; (b) 2.10 p.m.
