Nora left home at 7.15 a.m. and drove towards the theme park which was 1016 km away. For the first 408 km, she was travelling at 68 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 408 km
= 408 ÷ 68
= 6 h
Distance of the remaining journey
= 1016 - 408
= 608 km
Speed for remaining journey
= 68 + 8
= 76 km/h
Time taken to travel remaining journey
= 608 ÷ 76
= 8 h
Time taken to travel the whole journey
= 8 + 6
= 14 h
(b)
14 h after 7.15 a.m. = 9.15 p.m.
Answer(s): (a) 14 h; (b) 9.15 p.m.
