Kathy left home at 10.45 a.m. and drove towards the theme park which was 744 km away. For the first 264 km, she was travelling at 88 km/h. Then she increased her speed by 8 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 ÷ 88
= 3 h
Distance of the remaining journey
= 744 - 264
= 480 km
Speed for remaining journey
= 88 + 8
= 96 km/h
Time taken to travel remaining journey
= 480 ÷ 96
= 5 h
Time taken to travel the whole journey
= 5 + 3
= 8 h
(b)
8 h after 10.45 a.m. = 6.45 p.m.
Answer(s): (a) 8 h; (b) 6.45 p.m.
