Linda left home at 6.40 a.m. and drove towards the theme park which was 1096 km away. For the first 344 km, she was travelling at 86 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 344 km
= 344 ÷ 86
= 4 h
Distance of the remaining journey
= 1096 - 344
= 752 km
Speed for remaining journey
= 86 + 8
= 94 km/h
Time taken to travel remaining journey
= 752 ÷ 94
= 8 h
Time taken to travel the whole journey
= 8 + 4
= 12 h
(b)
12 h after 6.40 a.m. = 6.40 p.m.
Answer(s): (a) 12 h; (b) 6.40 p.m.
