At 10 54, Risa cycled from the hypermart towards the cinema while Shannon cycled from the cinema towards the hypermart. At 11 14, the two cyclists passed each other. 15 minutes later, Risa reached cinema but Shannon was 1130 m from the hypermart.
- At what combined speed were the two cyclists approaching each other?
- Find the distance between the cinema and the hypermart in km.
(a)
From 10 54 to 11 14 = 20 min
Combined speed of the two cyclists
= 1130 ÷ (20 - 15)
= 226 m/min
(b)
Distance between the cinema and the hypermart
= 20 x 226
= 4520 m
1000 m = 1 km
4520 m = 4.52 km
Distance between the cinema and the hypermart = 4.52 km
Answer(s): (a) 226 m/min; (b) 4.52 km
