Hilda usually takes a bus from her home to school. If she leaves home at 08 00, she will reach school at 09 47. 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 Hilda take to go school by the new MRT line?
- Hilda spent the next 3 h 55 min in school before dismissal. If Hilda started school at 09 25, at what time was she dismissed from school? Give your answer in the 12-hour clock format.
(a)
From 08 00 to 09 47: 1 h 47 min
Duration of Hilda's journey to go to school by the new MRT line
= 1 h 47 min - 20 min
= 107 min - 20 min
= 87 min
= 1 h 27 min
(b)
3 h 55 min after 09 25 = 13 20
13 20 = 1.20 p.m.
Time that Hilda was dismissed from school: 1.20 p.m.
Answer(s): (a) 1 h 27 min; (b) 1.20 p.m.
