Abi left home at 7.35 a.m. and drove towards the theme park which was 633 km away. For the first 268 km, she was travelling at 67 km/h. Then she increased her speed by 6 km/h and completed the remaining journey.
- How long did she take for her whole journey?
- At what time did she reach the theme park?
(a)
Time taken to travel 268 km
= 268 ÷ 67
= 4 h
Distance of the remaining journey
= 633 - 268
= 365 km
Speed for remaining journey
= 67 + 6
= 73 km/h
Time taken to travel remaining journey
= 365 ÷ 73
= 5 h
Time taken to travel the whole journey
= 5 + 4
= 9 h
(b)
9 h after 7.35 a.m. = 4.35 p.m.
Answer(s): (a) 9 h; (b) 4.35 p.m.
