At 12 58, Nora cycled from the library towards the cinema while Min cycled from the cinema towards the library. At 13 13, the two cyclists passed each other. 11 minutes later, Nora reached cinema but Min was 920 m from the library.
- At what combined speed were the two cyclists approaching each other?
- Find the distance between the cinema and the library in km.
(a)
From 12 58 to 13 13 = 15 min
Combined speed of the two cyclists
= 920 ÷ (15 - 11)
= 230 m/min
(b)
Distance between the cinema and the library
= 15 x 230
= 3450 m
1000 m = 1 km
3450 m = 3.45 km
Distance between the cinema and the library = 3.45 km
Answer(s): (a) 230 m/min; (b) 3.45 km
