At 11 55, Kylie cycled from the grocery store towards the church while Lucy cycled from the church towards the grocery store. At 12 11, the two cyclists passed each other. 14 minutes later, Kylie reached church but Lucy was 1200 m from the grocery store.
- At what combined speed were the two cyclists approaching each other?
- Find the distance between the church and the grocery store in km.
(a)
From 11 55 to 12 11 = 16 min
Combined speed of the two cyclists
= 1200 ÷ (16 - 14)
= 600 m/min
(b)
Distance between the church and the grocery store
= 16 x 600
= 9600 m
1000 m = 1 km
9600 m = 9.6 km
Distance between the church and the grocery store = 9.6 km
Answer(s): (a) 600 m/min; (b) 9.6 km
