Xandra left home at 9.50 a.m. and drove towards the theme park which was 566 km away. For the first 201 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 201 km
= 201 ÷ 67
= 3 h
Distance of the remaining journey
= 566 - 201
= 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 + 3
= 8 h
(b)
8 h after 9.50 a.m. = 5.50 p.m.
Answer(s): (a) 8 h; (b) 5.50 p.m.
