At 13 55, Mary cycled from the farm towards the cinema while Barbara cycled from the cinema towards the farm. At 14 15, the two cyclists passed each other. 10 minutes later, Mary reached cinema but Barbara was 1100 m from the farm.
- At what combined speed were the two cyclists approaching each other?
- Find the distance between the cinema and the farm in km.
(a)
From 13 55 to 14 15 = 20 min
Combined speed of the two cyclists
= 1100 ÷ (20 - 10)
= 110 m/min
(b)
Distance between the cinema and the farm
= 20 x 110
= 2200 m
1000 m = 1 km
2200 m = 2.2 km
Distance between the cinema and the farm = 2.2 km
Answer(s): (a) 110 m/min; (b) 2.2 km
