At 11 57, Sabrina cycled from the playground towards the market while Gillian cycled from the market towards the playground. At 12 11, the two cyclists passed each other. 9 minutes later, Sabrina reached market but Gillian was 1125 m from the playground.
- At what combined speed were the two cyclists approaching each other?
- Find the distance between the market and the playground in km.
(a)
From 11 57 to 12 11 = 14 min
Combined speed of the two cyclists
= 1125 ÷ (14 - 9)
= 225 m/min
(b)
Distance between the market and the playground
= 14 x 225
= 3150 m
1000 m = 1 km
3150 m = 3.15 km
Distance between the market and the playground = 3.15 km
Answer(s): (a) 225 m/min; (b) 3.15 km
