Jean left home at 7.50 a.m. and drove towards the theme park which was 444 km away. For the first 180 km, she was travelling at 60 km/h. Then she increased her speed by 6 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 180 km
= 180 ÷ 60
= 3 h
Distance of the remaining journey
= 444 - 180
= 264 km
Speed for remaining journey
= 60 + 6
= 66 km/h
Time taken to travel remaining journey
= 264 ÷ 66
= 4 h
Time taken to travel the whole journey
= 4 + 3
= 7 h
(b)
7 h after 7.50 a.m. = 2.50 p.m.
Answer(s): (a) 7 h; (b) 2.50 p.m.
