At 10 57, Sabrina cycled from the playground towards the cinema while Lynn cycled from the cinema towards the playground. At 11 15, the two cyclists passed each other. 13 minutes later, Sabrina reached cinema but Lynn was 950 m from the playground.
- At what combined speed were the two cyclists approaching each other?
- Find the distance between the cinema and the playground in km.
(a)
From 10 57 to 11 15 = 18 min
Combined speed of the two cyclists
= 950 ÷ (18 - 13)
= 190 m/min
(b)
Distance between the cinema and the playground
= 18 x 190
= 3420 m
1000 m = 1 km
3420 m = 3.42 km
Distance between the cinema and the playground = 3.42 km
Answer(s): (a) 190 m/min; (b) 3.42 km
