At 10 51, Elyse cycled from the playground towards the church while Jane cycled from the church towards the playground. At 11 11, the two cyclists passed each other. 15 minutes later, Elyse reached church but Jane was 1010 m from the playground.
- At what combined speed were the two cyclists approaching each other?
- Find the distance between the church and the playground in km.
(a)
From 10 51 to 11 11 = 20 min
Combined speed of the two cyclists
= 1010 ÷ (20 - 15)
= 202 m/min
(b)
Distance between the church and the playground
= 20 x 202
= 4040 m
1000 m = 1 km
4040 m = 4.04 km
Distance between the church and the playground = 4.04 km
Answer(s): (a) 202 m/min; (b) 4.04 km
