At 11 55, Shiyun cycled from the salon towards the cinema while Usha cycled from the cinema towards the salon. At 12 15, the two cyclists passed each other. 12 minutes later, Shiyun reached cinema but Usha was 984 m from the salon.
- At what combined speed were the two cyclists approaching each other?
- Find the distance between the cinema and the salon in km.
(a)
From 11 55 to 12 15 = 20 min
Combined speed of the two cyclists
= 984 ÷ (20 - 12)
= 123 m/min
(b)
Distance between the cinema and the salon
= 20 x 123
= 2460 m
1000 m = 1 km
2460 m = 2.46 km
Distance between the cinema and the salon = 2.46 km
Answer(s): (a) 123 m/min; (b) 2.46 km
