Hilda usually takes a bus from her home to school. If she leaves home at 07 00, she will reach school at 08 50. 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 Hilda take to go school by the new MRT line?
- Hilda spent the next 8 h 10 min in school before dismissal. If Hilda started school at 08 30, at what time was she dismissed from school? Give your answer in the 12-hour clock format.
(a)
From 07 00 to 08 50: 1 h 50 min
Duration of Hilda's journey to go to school by the new MRT line
= 1 h 50 min - 8 min
= 110 min - 8 min
= 102 min
= 1 h 42 min
(b)
8 h 10 min after 08 30 = 16 40
16 40 = 4.40 p.m.
Time that Hilda was dismissed from school: 4.40 p.m.
Answer(s): (a) 1 h 42 min; (b) 4.40 p.m.
