Hazel usually takes a bus from her home to school. If she leaves home at 05 00, she will reach school at 06 57. 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 Hazel take to go school by the new MRT line?
- Hazel spent the next 7 h 10 min in school before dismissal. If Hazel started school at 09 05, at what time was she dismissed from school? Give your answer in the 12-hour clock format.
(a)
From 05 00 to 06 57: 1 h 57 min
Duration of Hazel's journey to go to school by the new MRT line
= 1 h 57 min - 20 min
= 117 min - 20 min
= 97 min
= 1 h 37 min
(b)
7 h 10 min after 09 05 = 16 15
16 15 = 4.15 p.m.
Time that Hazel was dismissed from school: 4.15 p.m.
Answer(s): (a) 1 h 37 min; (b) 4.15 p.m.
