At 13 52, Jaslyn cycled from the cinema towards the playground while Fiona cycled from the playground towards the cinema. At 14 12, the two cyclists passed each other. 15 minutes later, Jaslyn reached playground but Fiona was 1090 m from the cinema.
- At what combined speed were the two cyclists approaching each other?
- Find the distance between the playground and the cinema in km.
(a)
From 13 52 to 14 12 = 20 min
Combined speed of the two cyclists
= 1090 ÷ (20 - 15)
= 218 m/min
(b)
Distance between the playground and the cinema
= 20 x 218
= 4360 m
1000 m = 1 km
4360 m = 4.36 km
Distance between the playground and the cinema = 4.36 km
Answer(s): (a) 218 m/min; (b) 4.36 km
