Flynn left City K for City J at 06 42. Fanny left City K for City C at the same time. At 11 42, they were 910 km apart. Both maintained a constant speed and reached their destination at the same time at 13 12.
- Find the distance between Cities A and C.
- If Fanny was 59 the speed of Flynn, find Flynn's speed.
(a)
Time taken for Flynn and Fanny to travel 06 42 to 11 42 = 5 h
Time taken for Flynn and Fanny to travel 06 42 to 13 12 = 6 h 30 min = 6
3060 h = 6
12 h
Distance travelled by Flynn and Fanny in 1 hour
= 910 ÷ 5
= 182 km
Total distance
= 6
12 x 182
= 1183 km
(b)
Fanny's distance : Flynn's distance
5 : 9
Fanny's speed : Flynn's speed
5 : 9
14 u = 182 km
1 u = 182 ÷ 14 = 13 km
Flynn's speed
= 9 u
= 9 x 13
= 117 km/h
Answer(s): (a) 1183 km; (b) 117km/h
