At 10 56, Hazel cycled from the mosque towards the playground while Yen cycled from the playground towards the mosque. At 11 16, the two cyclists passed each other. 15 minutes later, Hazel reached playground but Yen was 1150 m from the mosque.
- At what combined speed were the two cyclists approaching each other?
- Find the distance between the playground and the mosque in km.
(a)
From 10 56 to 11 16 = 20 min
Combined speed of the two cyclists
= 1150 ÷ (20 - 15)
= 230 m/min
(b)
Distance between the playground and the mosque
= 20 x 230
= 4600 m
1000 m = 1 km
4600 m = 4.6 km
Distance between the playground and the mosque = 4.6 km
Answer(s): (a) 230 m/min; (b) 4.6 km
