Kathy usually takes a bus from her home to school. If she leaves home at 05 00, she will reach school at 06 58. 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 13 min.
- How long does Kathy take to go school by the new MRT line?
- Kathy spent the next 3 h 30 min in school before dismissal. If Kathy started school at 09 45, at what time was she dismissed from school? Give your answer in the 12-hour clock format.
(a)
From 05 00 to 06 58: 1 h 58 min
Duration of Kathy's journey to go to school by the new MRT line
= 1 h 58 min - 13 min
= 118 min - 13 min
= 105 min
= 1 h 45 min
(b)
3 h 30 min after 09 45 = 13 15
13 15 = 1.15 p.m.
Time that Kathy was dismissed from school: 1.15 p.m.
Answer(s): (a) 1 h 45 min; (b) 1.15 p.m.
