At 10 52, Marion cycled from the playground towards the boutique while Yoko cycled from the boutique towards the playground. At 11 12, the two cyclists passed each other. 7 minutes later, Marion reached boutique but Yoko was 1092 m from the playground.
- At what combined speed were the two cyclists approaching each other?
- Find the distance between the boutique and the playground in km.
(a)
From 10 52 to 11 12 = 20 min
Combined speed of the two cyclists
= 1092 ÷ (20 - 7)
= 84 m/min
(b)
Distance between the boutique and the playground
= 20 x 84
= 1680 m
1000 m = 1 km
1680 m = 1.68 km
Distance between the boutique and the playground = 1.68 km
Answer(s): (a) 84 m/min; (b) 1.68 km
