At 11 53, Nicole cycled from the bank towards the cinema while Diana cycled from the cinema towards the bank. At 12 13, the two cyclists passed each other. 12 minutes later, Nicole reached cinema but Diana was 920 m from the bank.
- At what combined speed were the two cyclists approaching each other?
- Find the distance between the cinema and the bank in km.
(a)
From 11 53 to 12 13 = 20 min
Combined speed of the two cyclists
= 920 ÷ (20 - 12)
= 115 m/min
(b)
Distance between the cinema and the bank
= 20 x 115
= 2300 m
1000 m = 1 km
2300 m = 2.3 km
Distance between the cinema and the bank = 2.3 km
Answer(s): (a) 115 m/min; (b) 2.3 km
