Linda left home at 7.20 a.m. and drove towards the theme park which was 888 km away. For the first 516 km, she was travelling at 86 km/h. Then she increased her speed by 7 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 516 km
= 516 ÷ 86
= 6 h
Distance of the remaining journey
= 888 - 516
= 372 km
Speed for remaining journey
= 86 + 7
= 93 km/h
Time taken to travel remaining journey
= 372 ÷ 93
= 4 h
Time taken to travel the whole journey
= 4 + 6
= 10 h
(b)
10 h after 7.20 a.m. = 5.20 p.m.
Answer(s): (a) 10 h; (b) 5.20 p.m.
