Hilda usually takes a bus from her home to school. If she leaves home at 07 00, she will reach school at 08 40. 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 15 min.
- How long does Hilda take to go school by the new MRT line?
- Hilda spent the next 3 h 45 min in school before dismissal. If Hilda started school at 07 50, at what time was she dismissed from school? Give your answer in the 12-hour clock format.
(a)
From 07 00 to 08 40: 1 h 40 min
Duration of Hilda's journey to go to school by the new MRT line
= 1 h 40 min - 15 min
= 100 min - 15 min
= 85 min
= 1 h 25 min
(b)
3 h 45 min after 07 50 = 11 35
11 35 = 11.35 a.m.
Time that Hilda was dismissed from school: 11.35 a.m.
Answer(s): (a) 1 h 25 min; (b) 11.35 a.m.
