Risa usually takes a bus from her home to school. If she leaves home at 06 00, she will reach school at 07 36. 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 20 min.
- How long does Risa take to go school by the new MRT line?
- Risa spent the next 8 h 35 min in school before dismissal. If Risa started school at 08 50, at what time was she dismissed from school? Give your answer in the 12-hour clock format.
(a)
From 06 00 to 07 36: 1 h 36 min
Duration of Risa's journey to go to school by the new MRT line
= 1 h 36 min - 20 min
= 96 min - 20 min
= 76 min
= 1 h 16 min
(b)
8 h 35 min after 08 50 = 17 25
17 25 = 5.25 p.m.
Time that Risa was dismissed from school: 5.25 p.m.
Answer(s): (a) 1 h 16 min; (b) 5.25 p.m.
