Yen usually takes a bus from her home to school. If she leaves home at 05 00, she will reach school at 06 40. 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 25 min.
- How long does Yen take to go school by the new MRT line?
- Yen spent the next 5 h 5 min in school before dismissal. If Yen started school at 09 10, at what time was she dismissed from school? Give your answer in the 12-hour clock format.
(a)
From 05 00 to 06 40: 1 h 40 min
Duration of Yen's journey to go to school by the new MRT line
= 1 h 40 min - 25 min
= 100 min - 25 min
= 75 min
= 1 h 15 min
(b)
5 h 5 min after 09 10 = 14 15
14 15 = 2.15 p.m.
Time that Yen was dismissed from school: 2.15 p.m.
Answer(s): (a) 1 h 15 min; (b) 2.15 p.m.
