At 11 54, Gem cycled from the playground towards the bank while Lucy cycled from the bank towards the playground. At 12 14, the two cyclists passed each other. 15 minutes later, Gem reached bank but Lucy was 990 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 11 54 to 12 14 = 20 min
Combined speed of the two cyclists
= 990 ÷ (20 - 15)
= 198 m/min
(b)
Distance between the bank and the playground
= 20 x 198
= 3960 m
1000 m = 1 km
3960 m = 3.96 km
Distance between the bank and the playground = 3.96 km
Answer(s): (a) 198 m/min; (b) 3.96 km
