Fiona usually takes a bus from her home to school. If she leaves home at 05 00, she will reach school at 06 49. 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 3 min.
- How long does Fiona take to go school by the new MRT line?
- Fiona spent the next 7 h 5 min in school before dismissal. If Fiona started school at 09 10, at what time was she dismissed from school? Give your answer in the 12-hour clock format.
(a)
From 05 00 to 06 49: 1 h 49 min
Duration of Fiona's journey to go to school by the new MRT line
= 1 h 49 min - 3 min
= 109 min - 3 min
= 106 min
= 1 h 46 min
(b)
7 h 5 min after 09 10 = 16 15
16 15 = 4.15 p.m.
Time that Fiona was dismissed from school: 4.15 p.m.
Answer(s): (a) 1 h 46 min; (b) 4.15 p.m.
