Lucy usually takes a bus from her home to school. If she leaves home at 08 00, she will reach school at 09 42. 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 28 min.
- How long does Lucy take to go school by the new MRT line?
- Lucy spent the next 5 h 5 min in school before dismissal. If Lucy started school at 08 50, at what time was she dismissed from school? Give your answer in the 12-hour clock format.
(a)
From 08 00 to 09 42: 1 h 42 min
Duration of Lucy's journey to go to school by the new MRT line
= 1 h 42 min - 28 min
= 102 min - 28 min
= 74 min
= 1 h 14 min
(b)
5 h 5 min after 08 50 = 13 55
13 55 = 1.55 p.m.
Time that Lucy was dismissed from school: 1.55 p.m.
Answer(s): (a) 1 h 14 min; (b) 1.55 p.m.
