Tiffany usually takes a bus from her home to school. If she leaves home at 05 00, she will reach school at 06 35. 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 17 min.
- How long does Tiffany take to go school by the new MRT line?
- Tiffany spent the next 8 h 30 min in school before dismissal. If Tiffany started school at 08 50, at what time was she dismissed from school? Give your answer in the 12-hour clock format.
(a)
From 05 00 to 06 35: 1 h 35 min
Duration of Tiffany's journey to go to school by the new MRT line
= 1 h 35 min - 17 min
= 95 min - 17 min
= 78 min
= 1 h 18 min
(b)
8 h 30 min after 08 50 = 17 20
17 20 = 5.20 p.m.
Time that Tiffany was dismissed from school: 5.20 p.m.
Answer(s): (a) 1 h 18 min; (b) 5.20 p.m.
