Kathy usually takes a bus from her home to school. If she leaves home at 08 00, she will reach school at 09 37. 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 7 h 30 min in school before dismissal. If Kathy started school at 08 05, at what time was she dismissed from school? Give your answer in the 12-hour clock format.
(a)
From 08 00 to 09 37: 1 h 37 min
Duration of Kathy's journey to go to school by the new MRT line
= 1 h 37 min - 13 min
= 97 min - 13 min
= 84 min
= 1 h 24 min
(b)
7 h 30 min after 08 05 = 15 35
15 35 = 3.35 p.m.
Time that Kathy was dismissed from school: 3.35 p.m.
Answer(s): (a) 1 h 24 min; (b) 3.35 p.m.
