Esther usually takes a bus from her home to school. If she leaves home at 08 00, she will reach school at 09 32. 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 12 min.
- How long does Esther take to go school by the new MRT line?
- Esther spent the next 3 h 5 min in school before dismissal. If Esther started school at 07 40, at what time was she dismissed from school? Give your answer in the 12-hour clock format.
(a)
From 08 00 to 09 32: 1 h 32 min
Duration of Esther's journey to go to school by the new MRT line
= 1 h 32 min - 12 min
= 92 min - 12 min
= 80 min
= 1 h 20 min
(b)
3 h 5 min after 07 40 = 10 45
10 45 = 10.45 a.m.
Time that Esther was dismissed from school: 10.45 a.m.
Answer(s): (a) 1 h 20 min; (b) 10.45 a.m.
