Sarah usually takes a bus from her home to school. If she leaves home at 06 00, she will reach school at 07 46. 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 12 min.
- How long does Sarah take to go school by the new MRT line?
- Sarah spent the next 3 h 5 min in school before dismissal. If Sarah started school at 08 30, at what time was she dismissed from school? Give your answer in the 12-hour clock format.
(a)
From 06 00 to 07 46: 1 h 46 min
Duration of Sarah's journey to go to school by the new MRT line
= 1 h 46 min - 12 min
= 106 min - 12 min
= 94 min
= 1 h 34 min
(b)
3 h 5 min after 08 30 = 11 35
11 35 = 11.35 a.m.
Time that Sarah was dismissed from school: 11.35 a.m.
Answer(s): (a) 1 h 34 min; (b) 11.35 a.m.
