At 11 56, Lynn cycled from the mosque towards the park while Lucy cycled from the park towards the mosque. At 12 16, the two cyclists passed each other. 9 minutes later, Lynn reached park but Lucy was 1089 m from the mosque.
- At what combined speed were the two cyclists approaching each other?
- Find the distance between the park and the mosque in km.
(a)
From 11 56 to 12 16 = 20 min
Combined speed of the two cyclists
= 1089 ÷ (20 - 9)
= 99 m/min
(b)
Distance between the park and the mosque
= 20 x 99
= 1980 m
1000 m = 1 km
1980 m = 1.98 km
Distance between the park and the mosque = 1.98 km
Answer(s): (a) 99 m/min; (b) 1.98 km
