Shannon usually takes a bus from her home to school. If she leaves home at 06 00, she will reach school at 07 34. 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 21 min.
- How long does Shannon take to go school by the new MRT line?
- Shannon spent the next 3 h 55 min in school before dismissal. If Shannon started school at 09 25, at what time was she dismissed from school? Give your answer in the 12-hour clock format.
(a)
From 06 00 to 07 34: 1 h 34 min
Duration of Shannon's journey to go to school by the new MRT line
= 1 h 34 min - 21 min
= 94 min - 21 min
= 73 min
= 1 h 13 min
(b)
3 h 55 min after 09 25 = 13 20
13 20 = 1.20 p.m.
Time that Shannon was dismissed from school: 1.20 p.m.
Answer(s): (a) 1 h 13 min; (b) 1.20 p.m.
