At 12 59, Zoe cycled from the hospital towards the cinema while Olivia cycled from the cinema towards the hospital. At 13 16, the two cyclists passed each other. 15 minutes later, Zoe reached cinema but Olivia was 1000 m from the hospital.
- At what combined speed were the two cyclists approaching each other?
- Find the distance between the cinema and the hospital in km.
(a)
From 12 59 to 13 16 = 17 min
Combined speed of the two cyclists
= 1000 ÷ (17 - 15)
= 500 m/min
(b)
Distance between the cinema and the hospital
= 17 x 500
= 8500 m
1000 m = 1 km
8500 m = 8.5 km
Distance between the cinema and the hospital = 8.5 km
Answer(s): (a) 500 m/min; (b) 8.5 km
