Jen usually takes a bus from her home to school. If she leaves home at 06 00, she will reach school at 07 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 5 min.
- How long does Jen take to go school by the new MRT line?
- Jen spent the next 4 h 50 min in school before dismissal. If Jen started school at 08 40, at what time was she dismissed from school? Give your answer in the 12-hour clock format.
(a)
From 06 00 to 07 52: 1 h 52 min
Duration of Jen's journey to go to school by the new MRT line
= 1 h 52 min - 5 min
= 112 min - 5 min
= 107 min
= 1 h 47 min
(b)
4 h 50 min after 08 40 = 13 30
13 30 = 1.30 p.m.
Time that Jen was dismissed from school: 1.30 p.m.
Answer(s): (a) 1 h 47 min; (b) 1.30 p.m.
