At 13 58, Vanessa cycled from the bank towards the cinema while Marion cycled from the cinema towards the bank. At 14 18, the two cyclists passed each other. 8 minutes later, Vanessa reached cinema but Marion was 1020 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 13 58 to 14 18 = 20 min
Combined speed of the two cyclists
= 1020 ÷ (20 - 8)
= 85 m/min
(b)
Distance between the cinema and the bank
= 20 x 85
= 1700 m
1000 m = 1 km
1700 m = 1.7 km
Distance between the cinema and the bank = 1.7 km
Answer(s): (a) 85 m/min; (b) 1.7 km
