At 13 56, Elyse cycled from the playground towards the bank while Xylia cycled from the bank towards the playground. At 14 16, the two cyclists passed each other. 9 minutes later, Elyse reached bank but Xylia was 1100 m from the playground.
- At what combined speed were the two cyclists approaching each other?
- Find the distance between the bank and the playground in km.
(a)
From 13 56 to 14 16 = 20 min
Combined speed of the two cyclists
= 1100 ÷ (20 - 9)
= 100 m/min
(b)
Distance between the bank and the playground
= 20 x 100
= 2000 m
1000 m = 1 km
2000 m = 2 km
Distance between the bank and the playground = 2 km
Answer(s): (a) 100 m/min; (b) 2 km
