At 13 53, Betty cycled from the cafe towards the park while Opal cycled from the park towards the cafe. At 14 13, the two cyclists passed each other. 11 minutes later, Betty reached park but Opal was 972 m from the cafe.
- At what combined speed were the two cyclists approaching each other?
- Find the distance between the park and the cafe in km.
(a)
From 13 53 to 14 13 = 20 min
Combined speed of the two cyclists
= 972 ÷ (20 - 11)
= 108 m/min
(b)
Distance between the park and the cafe
= 20 x 108
= 2160 m
1000 m = 1 km
2160 m = 2.16 km
Distance between the park and the cafe = 2.16 km
Answer(s): (a) 108 m/min; (b) 2.16 km
