Hazel left home at 8.20 a.m. and drove towards the theme park which was 1043 km away. For the first 267 km, she was travelling at 89 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 267 km
= 267 ÷ 89
= 3 h
Distance of the remaining journey
= 1043 - 267
= 776 km
Speed for remaining journey
= 89 + 8
= 97 km/h
Time taken to travel remaining journey
= 776 ÷ 97
= 8 h
Time taken to travel the whole journey
= 8 + 3
= 11 h
(b)
11 h after 8.20 a.m. = 7.20 p.m.
Answer(s): (a) 11 h; (b) 7.20 p.m.
