At 11 52, Elyse cycled from the hypermart towards the playground while Fanny cycled from the playground towards the hypermart. At 12 12, the two cyclists passed each other. 13 minutes later, Elyse reached playground but Fanny was 980 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 11 52 to 12 12 = 20 min
Combined speed of the two cyclists
= 980 ÷ (20 - 13)
= 140 m/min
(b)
Distance between the playground and the hypermart
= 20 x 140
= 2800 m
1000 m = 1 km
2800 m = 2.8 km
Distance between the playground and the hypermart = 2.8 km
Answer(s): (a) 140 m/min; (b) 2.8 km
