Zoe left home at 6.35 a.m. and drove towards the theme park which was 956 km away. For the first 252 km, she was travelling at 84 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 252 km
= 252 ÷ 84
= 3 h
Distance of the remaining journey
= 956 - 252
= 704 km
Speed for remaining journey
= 84 + 4
= 88 km/h
Time taken to travel remaining journey
= 704 ÷ 88
= 8 h
Time taken to travel the whole journey
= 8 + 3
= 11 h
(b)
11 h after 6.35 a.m. = 5.35 p.m.
Answer(s): (a) 11 h; (b) 5.35 p.m.
