At 13 53, Jean cycled from the hypermart towards the grocery store while Kathy cycled from the grocery store towards the hypermart. At 14 12, the two cyclists passed each other. 7 minutes later, Jean reached grocery store but Kathy was 1200 m from the hypermart.
- At what combined speed were the two cyclists approaching each other?
- Find the distance between the grocery store and the hypermart in km.
(a)
From 13 53 to 14 12 = 19 min
Combined speed of the two cyclists
= 1200 ÷ (19 - 7)
= 100 m/min
(b)
Distance between the grocery store and the hypermart
= 19 x 100
= 1900 m
1000 m = 1 km
1900 m = 1.9 km
Distance between the grocery store and the hypermart = 1.9 km
Answer(s): (a) 100 m/min; (b) 1.9 km
