Wendy usually takes a bus from her home to school. If she leaves home at 07 00, she will reach school at 08 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 18 min.
- How long does Wendy take to go school by the new MRT line?
- Wendy spent the next 5 h 45 min in school before dismissal. If Wendy started school at 09 50, at what time was she dismissed from school? Give your answer in the 12-hour clock format.
(a)
From 07 00 to 08 42: 1 h 42 min
Duration of Wendy's journey to go to school by the new MRT line
= 1 h 42 min - 18 min
= 102 min - 18 min
= 84 min
= 1 h 24 min
(b)
5 h 45 min after 09 50 = 15 35
15 35 = 3.35 p.m.
Time that Wendy was dismissed from school: 3.35 p.m.
Answer(s): (a) 1 h 24 min; (b) 3.35 p.m.
