Gwen usually takes a bus from her home to school. If she leaves home at 07 00, she will reach school at 08 56. 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 10 min.
- How long does Gwen take to go school by the new MRT line?
- Gwen spent the next 4 h 5 min in school before dismissal. If Gwen started school at 09 45, at what time was she dismissed from school? Give your answer in the 12-hour clock format.
(a)
From 07 00 to 08 56: 1 h 56 min
Duration of Gwen's journey to go to school by the new MRT line
= 1 h 56 min - 10 min
= 116 min - 10 min
= 106 min
= 1 h 46 min
(b)
4 h 5 min after 09 45 = 13 50
13 50 = 1.50 p.m.
Time that Gwen was dismissed from school: 1.50 p.m.
Answer(s): (a) 1 h 46 min; (b) 1.50 p.m.
