At 12 54, Yen cycled from the cinema towards the park while Opal cycled from the park towards the cinema. At 13 14, the two cyclists passed each other. 12 minutes later, Yen reached park but Opal was 1152 m from the cinema.
- At what combined speed were the two cyclists approaching each other?
- Find the distance between the park and the cinema in km.
(a)
From 12 54 to 13 14 = 20 min
Combined speed of the two cyclists
= 1152 ÷ (20 - 12)
= 144 m/min
(b)
Distance between the park and the cinema
= 20 x 144
= 2880 m
1000 m = 1 km
2880 m = 2.88 km
Distance between the park and the cinema = 2.88 km
Answer(s): (a) 144 m/min; (b) 2.88 km
