Vanessa usually takes a bus from her home to school. If she leaves home at 06 00, she will reach school at 07 40. 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 15 min.
- How long does Vanessa take to go school by the new MRT line?
- Vanessa spent the next 3 h 40 min in school before dismissal. If Vanessa started school at 08 40, at what time was she dismissed from school? Give your answer in the 12-hour clock format.
(a)
From 06 00 to 07 40: 1 h 40 min
Duration of Vanessa's journey to go to school by the new MRT line
= 1 h 40 min - 15 min
= 100 min - 15 min
= 85 min
= 1 h 25 min
(b)
3 h 40 min after 08 40 = 12 20
12 20 = 12.20 p.m.
Time that Vanessa was dismissed from school: 12.20 p.m.
Answer(s): (a) 1 h 25 min; (b) 12.20 p.m.
