Irene usually takes a bus from her home to school. If she leaves home at 08 00, she will reach school at 09 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 1 min.
- How long does Irene take to go school by the new MRT line?
- Irene spent the next 5 h 45 min in school before dismissal. If Irene started school at 08 15, at what time was she dismissed from school? Give your answer in the 12-hour clock format.
(a)
From 08 00 to 09 40: 1 h 40 min
Duration of Irene's journey to go to school by the new MRT line
= 1 h 40 min - 1 min
= 100 min - 1 min
= 99 min
= 1 h 39 min
(b)
5 h 45 min after 08 15 = 14 00
14 00 = 2.00 p.m.
Time that Irene was dismissed from school: 2.00 p.m.
Answer(s): (a) 1 h 39 min; (b) 2.00 p.m.
