Gillian usually takes a bus from her home to school. If she leaves home at 08 00, she will reach school at 09 47. 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 Gillian take to go school by the new MRT line?
- Gillian spent the next 8 h 30 min in school before dismissal. If Gillian started school at 09 50, at what time was she dismissed from school? Give your answer in the 12-hour clock format.
(a)
From 08 00 to 09 47: 1 h 47 min
Duration of Gillian's journey to go to school by the new MRT line
= 1 h 47 min - 26 min
= 107 min - 26 min
= 81 min
= 1 h 21 min
(b)
8 h 30 min after 09 50 = 18 20
18 20 = 6.20 p.m.
Time that Gillian was dismissed from school: 6.20 p.m.
Answer(s): (a) 1 h 21 min; (b) 6.20 p.m.
