Lucy usually takes a bus from her home to school. If she leaves home at 08 00, she will reach school at 09 34. 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 Lucy take to go school by the new MRT line?
- Lucy spent the next 4 h 20 min in school before dismissal. If Lucy started school at 09 50, at what time was she dismissed from school? Give your answer in the 12-hour clock format.
(a)
From 08 00 to 09 34: 1 h 34 min
Duration of Lucy's journey to go to school by the new MRT line
= 1 h 34 min - 12 min
= 94 min - 12 min
= 82 min
= 1 h 22 min
(b)
4 h 20 min after 09 50 = 14 10
14 10 = 2.10 p.m.
Time that Lucy was dismissed from school: 2.10 p.m.
Answer(s): (a) 1 h 22 min; (b) 2.10 p.m.
