Pamela left home at 7.50 a.m. and drove towards the theme park which was 940 km away. For the first 408 km, she was travelling at 68 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 408 km
= 408 ÷ 68
= 6 h
Distance of the remaining journey
= 940 - 408
= 532 km
Speed for remaining journey
= 68 + 8
= 76 km/h
Time taken to travel remaining journey
= 532 ÷ 76
= 7 h
Time taken to travel the whole journey
= 7 + 6
= 13 h
(b)
13 h after 7.50 a.m. = 8.50 p.m.
Answer(s): (a) 13 h; (b) 8.50 p.m.
