Sabrina usually takes a bus from her home to school. If she leaves home at 08 00, she will reach school at 09 48. 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 14 min.
- How long does Sabrina take to go school by the new MRT line?
- Sabrina spent the next 7 h 10 min in school before dismissal. If Sabrina started school at 07 20, at what time was she dismissed from school? Give your answer in the 12-hour clock format.
(a)
From 08 00 to 09 48: 1 h 48 min
Duration of Sabrina's journey to go to school by the new MRT line
= 1 h 48 min - 14 min
= 108 min - 14 min
= 94 min
= 1 h 34 min
(b)
7 h 10 min after 07 20 = 14 30
14 30 = 2.30 p.m.
Time that Sabrina was dismissed from school: 2.30 p.m.
Answer(s): (a) 1 h 34 min; (b) 2.30 p.m.
