Kathy usually takes a bus from her home to school. If she leaves home at 05 00, she will reach school at 06 44. 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 23 min.
- How long does Kathy take to go school by the new MRT line?
- Kathy spent the next 5 h 45 min in school before dismissal. If Kathy started school at 07 20, at what time was she dismissed from school? Give your answer in the 12-hour clock format.
(a)
From 05 00 to 06 44: 1 h 44 min
Duration of Kathy's journey to go to school by the new MRT line
= 1 h 44 min - 23 min
= 104 min - 23 min
= 81 min
= 1 h 21 min
(b)
5 h 45 min after 07 20 = 13 05
13 05 = 1.05 p.m.
Time that Kathy was dismissed from school: 1.05 p.m.
Answer(s): (a) 1 h 21 min; (b) 1.05 p.m.
