Dana usually takes a bus from her home to school. If she leaves home at 05 00, she will reach school at 06 52. 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 7 min.
- How long does Dana take to go school by the new MRT line?
- Dana spent the next 7 h 45 min in school before dismissal. If Dana started school at 09 45, at what time was she dismissed from school? Give your answer in the 12-hour clock format.
(a)
From 05 00 to 06 52: 1 h 52 min
Duration of Dana's journey to go to school by the new MRT line
= 1 h 52 min - 7 min
= 112 min - 7 min
= 105 min
= 1 h 45 min
(b)
7 h 45 min after 09 45 = 17 30
17 30 = 5.30 p.m.
Time that Dana was dismissed from school: 5.30 p.m.
Answer(s): (a) 1 h 45 min; (b) 5.30 p.m.
