Usha usually takes a bus from her home to school. If she leaves home at 08 00, she will reach school at 09 37. 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 Usha take to go school by the new MRT line?
- Usha spent the next 4 h 50 min in school before dismissal. If Usha started school at 09 45, at what time was she dismissed from school? Give your answer in the 12-hour clock format.
(a)
From 08 00 to 09 37: 1 h 37 min
Duration of Usha's journey to go to school by the new MRT line
= 1 h 37 min - 21 min
= 97 min - 21 min
= 76 min
= 1 h 16 min
(b)
4 h 50 min after 09 45 = 14 35
14 35 = 2.35 p.m.
Time that Usha was dismissed from school: 2.35 p.m.
Answer(s): (a) 1 h 16 min; (b) 2.35 p.m.
