At 10 56, Kathy cycled from the bistro towards the grocery store while Lucy cycled from the grocery store towards the bistro. At 11 16, the two cyclists passed each other. 13 minutes later, Kathy reached grocery store but Lucy was 1071 m from the bistro.
- At what combined speed were the two cyclists approaching each other?
- Find the distance between the grocery store and the bistro in km.
(a)
From 10 56 to 11 16 = 20 min
Combined speed of the two cyclists
= 1071 ÷ (20 - 13)
= 153 m/min
(b)
Distance between the grocery store and the bistro
= 20 x 153
= 3060 m
1000 m = 1 km
3060 m = 3.06 km
Distance between the grocery store and the bistro = 3.06 km
Answer(s): (a) 153 m/min; (b) 3.06 km
