At 11 59, Marion cycled from the boutique towards the grocery store while Yen cycled from the grocery store towards the boutique. At 12 19, the two cyclists passed each other. 13 minutes later, Marion reached grocery store but Yen was 1148 m from the boutique.
- At what combined speed were the two cyclists approaching each other?
- Find the distance between the grocery store and the boutique in km.
(a)
From 11 59 to 12 19 = 20 min
Combined speed of the two cyclists
= 1148 ÷ (20 - 13)
= 164 m/min
(b)
Distance between the grocery store and the boutique
= 20 x 164
= 3280 m
1000 m = 1 km
3280 m = 3.28 km
Distance between the grocery store and the boutique = 3.28 km
Answer(s): (a) 164 m/min; (b) 3.28 km
