At 13 59, Tina cycled from the boutique towards the library while Kylie cycled from the library towards the boutique. At 14 15, the two cyclists passed each other. 14 minutes later, Tina reached library but Kylie was 1080 m from the boutique.
- At what combined speed were the two cyclists approaching each other?
- Find the distance between the library and the boutique in km.
(a)
From 13 59 to 14 15 = 16 min
Combined speed of the two cyclists
= 1080 ÷ (16 - 14)
= 540 m/min
(b)
Distance between the library and the boutique
= 16 x 540
= 8640 m
1000 m = 1 km
8640 m = 8.64 km
Distance between the library and the boutique = 8.64 km
Answer(s): (a) 540 m/min; (b) 8.64 km
