Cathy usually takes a bus from her home to school. If she leaves home at 08 00, she will reach school at 09 43. 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 26 min.
- How long does Cathy take to go school by the new MRT line?
- Cathy spent the next 3 h 30 min in school before dismissal. If Cathy started school at 08 55, at what time was she dismissed from school? Give your answer in the 12-hour clock format.
(a)
From 08 00 to 09 43: 1 h 43 min
Duration of Cathy's journey to go to school by the new MRT line
= 1 h 43 min - 26 min
= 103 min - 26 min
= 77 min
= 1 h 17 min
(b)
3 h 30 min after 08 55 = 12 25
12 25 = 12.25 p.m.
Time that Cathy was dismissed from school: 12.25 p.m.
Answer(s): (a) 1 h 17 min; (b) 12.25 p.m.
