Yoko usually takes a bus from her home to school. If she leaves home at 06 00, she will reach school at 07 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 9 min.
- How long does Yoko take to go school by the new MRT line?
- Yoko spent the next 4 h 40 min in school before dismissal. If Yoko started school at 09 15, at what time was she dismissed from school? Give your answer in the 12-hour clock format.
(a)
From 06 00 to 07 42: 1 h 42 min
Duration of Yoko's journey to go to school by the new MRT line
= 1 h 42 min - 9 min
= 102 min - 9 min
= 93 min
= 1 h 33 min
(b)
4 h 40 min after 09 15 = 13 55
13 55 = 1.55 p.m.
Time that Yoko was dismissed from school: 1.55 p.m.
Answer(s): (a) 1 h 33 min; (b) 1.55 p.m.
