Gabby usually takes a bus from her home to school. If she leaves home at 06 00, she will reach school at 07 30. 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 1 min.
- How long does Gabby take to go school by the new MRT line?
- Gabby spent the next 6 h 55 min in school before dismissal. If Gabby started school at 07 45, at what time was she dismissed from school? Give your answer in the 12-hour clock format.
(a)
From 06 00 to 07 30: 1 h 30 min
Duration of Gabby's journey to go to school by the new MRT line
= 1 h 30 min - 1 min
= 90 min - 1 min
= 89 min
= 1 h 29 min
(b)
6 h 55 min after 07 45 = 14 40
14 40 = 2.40 p.m.
Time that Gabby was dismissed from school: 2.40 p.m.
Answer(s): (a) 1 h 29 min; (b) 2.40 p.m.
