Erika usually takes a bus from her home to school. If she leaves home at 08 00, she will reach school at 09 50. 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 8 min.
- How long does Erika take to go school by the new MRT line?
- Erika spent the next 4 h 55 min in school before dismissal. If Erika started school at 07 05, at what time was she dismissed from school? Give your answer in the 12-hour clock format.
(a)
From 08 00 to 09 50: 1 h 50 min
Duration of Erika's journey to go to school by the new MRT line
= 1 h 50 min - 8 min
= 110 min - 8 min
= 102 min
= 1 h 42 min
(b)
4 h 55 min after 07 05 = 12 00
12 00 = 12.00 p.m.
Time that Erika was dismissed from school: 12.00 p.m.
Answer(s): (a) 1 h 42 min; (b) 12.00 p.m.
