Yoko usually takes a bus from her home to school. If she leaves home at 05 00, she will reach school at 06 34. 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 15 min.
- How long does Yoko take to go school by the new MRT line?
- Yoko spent the next 6 h 55 min in school before dismissal. If Yoko started school at 09 40, at what time was she dismissed from school? Give your answer in the 12-hour clock format.
(a)
From 05 00 to 06 34: 1 h 34 min
Duration of Yoko's journey to go to school by the new MRT line
= 1 h 34 min - 15 min
= 94 min - 15 min
= 79 min
= 1 h 19 min
(b)
6 h 55 min after 09 40 = 16 35
16 35 = 4.35 p.m.
Time that Yoko was dismissed from school: 4.35 p.m.
Answer(s): (a) 1 h 19 min; (b) 4.35 p.m.
