Irene usually takes a bus from her home to school. If she leaves home at 07 00, she will reach school at 08 41. 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 8 min.
- How long does Irene take to go school by the new MRT line?
- Irene spent the next 7 h 50 min in school before dismissal. If Irene started school at 08 35, at what time was she dismissed from school? Give your answer in the 12-hour clock format.
(a)
From 07 00 to 08 41: 1 h 41 min
Duration of Irene's journey to go to school by the new MRT line
= 1 h 41 min - 8 min
= 101 min - 8 min
= 93 min
= 1 h 33 min
(b)
7 h 50 min after 08 35 = 16 25
16 25 = 4.25 p.m.
Time that Irene was dismissed from school: 4.25 p.m.
Answer(s): (a) 1 h 33 min; (b) 4.25 p.m.
