Betty usually takes a bus from her home to school. If she leaves home at 06 00, she will reach school at 07 45. 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 17 min.
- How long does Betty take to go school by the new MRT line?
- Betty spent the next 3 h 5 min in school before dismissal. If Betty started school at 09 05, at what time was she dismissed from school? Give your answer in the 12-hour clock format.
(a)
From 06 00 to 07 45: 1 h 45 min
Duration of Betty's journey to go to school by the new MRT line
= 1 h 45 min - 17 min
= 105 min - 17 min
= 88 min
= 1 h 28 min
(b)
3 h 5 min after 09 05 = 12 10
12 10 = 12.10 p.m.
Time that Betty was dismissed from school: 12.10 p.m.
Answer(s): (a) 1 h 28 min; (b) 12.10 p.m.
