Raeann left home at 8.40 a.m. and drove towards the theme park which was 944 km away. For the first 240 km, she was travelling at 80 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 240 km
= 240 ÷ 80
= 3 h
Distance of the remaining journey
= 944 - 240
= 704 km
Speed for remaining journey
= 80 + 8
= 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 8.40 a.m. = 7.40 p.m.
Answer(s): (a) 11 h; (b) 7.40 p.m.
