At 11 58, Hilda cycled from the hypermart towards the cinema while Kylie cycled from the cinema towards the hypermart. At 12 18, the two cyclists passed each other. 11 minutes later, Hilda reached cinema but Kylie was 918 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 11 58 to 12 18 = 20 min
Combined speed of the two cyclists
= 918 ÷ (20 - 11)
= 102 m/min
(b)
Distance between the cinema and the hypermart
= 20 x 102
= 2040 m
1000 m = 1 km
2040 m = 2.04 km
Distance between the cinema and the hypermart = 2.04 km
Answer(s): (a) 102 m/min; (b) 2.04 km
