Barbara left home at 9.45 a.m. and drove towards the theme park which was 1197 km away. For the first 445 km, she was travelling at 89 km/h. Then she increased her speed by 5 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 445 km
= 445 ÷ 89
= 5 h
Distance of the remaining journey
= 1197 - 445
= 752 km
Speed for remaining journey
= 89 + 5
= 94 km/h
Time taken to travel remaining journey
= 752 ÷ 94
= 8 h
Time taken to travel the whole journey
= 8 + 5
= 13 h
(b)
13 h after 9.45 a.m. = 10.45 p.m.
Answer(s): (a) 13 h; (b) 10.45 p.m.
