Jaslyn left home at 6.15 a.m. and drove towards the theme park which was 696 km away. For the first 264 km, she was travelling at 66 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 264 km
= 264 ÷ 66
= 4 h
Distance of the remaining journey
= 696 - 264
= 432 km
Speed for remaining journey
= 66 + 6
= 72 km/h
Time taken to travel remaining journey
= 432 ÷ 72
= 6 h
Time taken to travel the whole journey
= 6 + 4
= 10 h
(b)
10 h after 6.15 a.m. = 4.15 p.m.
Answer(s): (a) 10 h; (b) 4.15 p.m.
