Jade left home at 6.20 a.m. and drove towards the theme park which was 955 km away. For the first 332 km, she was travelling at 83 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 332 km
= 332 ÷ 83
= 4 h
Distance of the remaining journey
= 955 - 332
= 623 km
Speed for remaining journey
= 83 + 6
= 89 km/h
Time taken to travel remaining journey
= 623 ÷ 89
= 7 h
Time taken to travel the whole journey
= 7 + 4
= 11 h
(b)
11 h after 6.20 a.m. = 5.20 p.m.
Answer(s): (a) 11 h; (b) 5.20 p.m.
