Roshel 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 20 min.
- How long does Roshel take to go school by the new MRT line?
- Roshel spent the next 6 h 40 min in school before dismissal. If Roshel started school at 09 40, 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 Roshel's journey to go to school by the new MRT line
= 1 h 38 min - 20 min
= 98 min - 20 min
= 78 min
= 1 h 18 min
(b)
6 h 40 min after 09 40 = 16 20
16 20 = 4.20 p.m.
Time that Roshel was dismissed from school: 4.20 p.m.
Answer(s): (a) 1 h 18 min; (b) 4.20 p.m.
