Hazel usually takes a bus from her home to school. If she leaves home at 06 00, she will reach school at 07 31. 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 17 min.
- How long does Hazel take to go school by the new MRT line?
- Hazel spent the next 8 h 30 min in school before dismissal. If Hazel started school at 09 25, at what time was she dismissed from school? Give your answer in the 12-hour clock format.
(a)
From 06 00 to 07 31: 1 h 31 min
Duration of Hazel's journey to go to school by the new MRT line
= 1 h 31 min - 17 min
= 91 min - 17 min
= 74 min
= 1 h 14 min
(b)
8 h 30 min after 09 25 = 17 55
17 55 = 5.55 p.m.
Time that Hazel was dismissed from school: 5.55 p.m.
Answer(s): (a) 1 h 14 min; (b) 5.55 p.m.
