Zara left home at 8.10 a.m. and drove towards the theme park which was 1068 km away. For the first 480 km, she was travelling at 80 km/h. Then she increased her speed by 4 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 480 km
= 480 ÷ 80
= 6 h
Distance of the remaining journey
= 1068 - 480
= 588 km
Speed for remaining journey
= 80 + 4
= 84 km/h
Time taken to travel remaining journey
= 588 ÷ 84
= 7 h
Time taken to travel the whole journey
= 7 + 6
= 13 h
(b)
13 h after 8.10 a.m. = 9.10 p.m.
Answer(s): (a) 13 h; (b) 9.10 p.m.
