At 13 52, Ivory cycled from the playground towards the school while Tammy cycled from the school towards the playground. At 14 12, the two cyclists passed each other. 8 minutes later, Ivory reached school but Tammy was 1164 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 13 52 to 14 12 = 20 min
Combined speed of the two cyclists
= 1164 ÷ (20 - 8)
= 97 m/min
(b)
Distance between the school and the playground
= 20 x 97
= 1940 m
1000 m = 1 km
1940 m = 1.94 km
Distance between the school and the playground = 1.94 km
Answer(s): (a) 97 m/min; (b) 1.94 km
