Raeann usually takes a bus from her home to school. If she leaves home at 08 00, she will reach school at 09 34. 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 19 min.
- How long does Raeann take to go school by the new MRT line?
- Raeann spent the next 3 h 40 min in school before dismissal. If Raeann started school at 07 20, at what time was she dismissed from school? Give your answer in the 12-hour clock format.
(a)
From 08 00 to 09 34: 1 h 34 min
Duration of Raeann's journey to go to school by the new MRT line
= 1 h 34 min - 19 min
= 94 min - 19 min
= 75 min
= 1 h 15 min
(b)
3 h 40 min after 07 20 = 11 00
11 00 = 11.00 a.m.
Time that Raeann was dismissed from school: 11.00 a.m.
Answer(s): (a) 1 h 15 min; (b) 11.00 a.m.
