At 12 56, Wendy cycled from the grocery store towards the cafe while Fiona cycled from the cafe towards the grocery store. At 13 16, the two cyclists passed each other. 15 minutes later, Wendy reached cafe but Fiona was 960 m from the grocery store.
- At what combined speed were the two cyclists approaching each other?
- Find the distance between the cafe and the grocery store in km.
(a)
From 12 56 to 13 16 = 20 min
Combined speed of the two cyclists
= 960 ÷ (20 - 15)
= 192 m/min
(b)
Distance between the cafe and the grocery store
= 20 x 192
= 3840 m
1000 m = 1 km
3840 m = 3.84 km
Distance between the cafe and the grocery store = 3.84 km
Answer(s): (a) 192 m/min; (b) 3.84 km
