At 10 57, Lynn cycled from the mosque towards the church while Nora cycled from the church towards the mosque. At 11 12, the two cyclists passed each other. 9 minutes later, Lynn reached church but Nora was 1128 m from the mosque.
- At what combined speed were the two cyclists approaching each other?
- Find the distance between the church and the mosque in km.
(a)
From 10 57 to 11 12 = 15 min
Combined speed of the two cyclists
= 1128 ÷ (15 - 9)
= 188 m/min
(b)
Distance between the church and the mosque
= 15 x 188
= 2820 m
1000 m = 1 km
2820 m = 2.82 km
Distance between the church and the mosque = 2.82 km
Answer(s): (a) 188 m/min; (b) 2.82 km
