Sarah usually takes a bus from her home to school. If she leaves home at 06 00, she will reach school at 07 36. 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 11 min.
- How long does Sarah take to go school by the new MRT line?
- Sarah spent the next 7 h 25 min in school before dismissal. If Sarah started school at 07 40, at what time was she dismissed from school? Give your answer in the 12-hour clock format.
(a)
From 06 00 to 07 36: 1 h 36 min
Duration of Sarah's journey to go to school by the new MRT line
= 1 h 36 min - 11 min
= 96 min - 11 min
= 85 min
= 1 h 25 min
(b)
7 h 25 min after 07 40 = 15 05
15 05 = 3.05 p.m.
Time that Sarah was dismissed from school: 3.05 p.m.
Answer(s): (a) 1 h 25 min; (b) 3.05 p.m.
