At 11 58, Erika cycled from the playground towards the school while Lucy cycled from the school towards the playground. At 12 13, the two cyclists passed each other. 13 minutes later, Erika reached school but Lucy was 1136 m from the playground.
- At what combined speed were the two cyclists approaching each other?
- Find the distance between the school and the playground in km.
(a)
From 11 58 to 12 13 = 15 min
Combined speed of the two cyclists
= 1136 ÷ (15 - 13)
= 568 m/min
(b)
Distance between the school and the playground
= 15 x 568
= 8520 m
1000 m = 1 km
8520 m = 8.52 km
Distance between the school and the playground = 8.52 km
Answer(s): (a) 568 m/min; (b) 8.52 km
