Jen usually takes a bus from her home to school. If she leaves home at 06 00, she will reach school at 07 38. 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 17 min.
- How long does Jen take to go school by the new MRT line?
- Jen spent the next 6 h 5 min in school before dismissal. If Jen started school at 09 30, at what time was she dismissed from school? Give your answer in the 12-hour clock format.
(a)
From 06 00 to 07 38: 1 h 38 min
Duration of Jen's journey to go to school by the new MRT line
= 1 h 38 min - 17 min
= 98 min - 17 min
= 81 min
= 1 h 21 min
(b)
6 h 5 min after 09 30 = 15 35
15 35 = 3.35 p.m.
Time that Jen was dismissed from school: 3.35 p.m.
Answer(s): (a) 1 h 21 min; (b) 3.35 p.m.
