At 12 56, Kathy cycled from the grocery store towards the park while Tammy cycled from the park towards the grocery store. At 13 12, the two cyclists passed each other. 11 minutes later, Kathy reached park but Tammy was 1125 m from the grocery store.
- At what combined speed were the two cyclists approaching each other?
- Find the distance between the park and the grocery store in km.
(a)
From 12 56 to 13 12 = 16 min
Combined speed of the two cyclists
= 1125 ÷ (16 - 11)
= 225 m/min
(b)
Distance between the park and the grocery store
= 16 x 225
= 3600 m
1000 m = 1 km
3600 m = 3.6 km
Distance between the park and the grocery store = 3.6 km
Answer(s): (a) 225 m/min; (b) 3.6 km
