At 12 52, Zoe cycled from the hypermart towards the playground while Usha cycled from the playground towards the hypermart. At 13 12, the two cyclists passed each other. 14 minutes later, Zoe reached playground but Usha was 1182 m from the hypermart.
- At what combined speed were the two cyclists approaching each other?
- Find the distance between the playground and the hypermart in km.
(a)
From 12 52 to 13 12 = 20 min
Combined speed of the two cyclists
= 1182 ÷ (20 - 14)
= 197 m/min
(b)
Distance between the playground and the hypermart
= 20 x 197
= 3940 m
1000 m = 1 km
3940 m = 3.94 km
Distance between the playground and the hypermart = 3.94 km
Answer(s): (a) 197 m/min; (b) 3.94 km
