Dana usually takes a bus from her home to school. If she leaves home at 07 00, she will reach school at 08 53. 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 10 min.
- How long does Dana take to go school by the new MRT line?
- Dana spent the next 4 h 20 min in school before dismissal. If Dana started school at 08 05, at what time was she dismissed from school? Give your answer in the 12-hour clock format.
(a)
From 07 00 to 08 53: 1 h 53 min
Duration of Dana's journey to go to school by the new MRT line
= 1 h 53 min - 10 min
= 113 min - 10 min
= 103 min
= 1 h 43 min
(b)
4 h 20 min after 08 05 = 12 25
12 25 = 12.25 p.m.
Time that Dana was dismissed from school: 12.25 p.m.
Answer(s): (a) 1 h 43 min; (b) 12.25 p.m.
