At 12 56, Hazel cycled from the playground towards the bistro while Cathy cycled from the bistro towards the playground. At 13 16, the two cyclists passed each other. 10 minutes later, Hazel reached bistro but Cathy was 990 m from the playground.
- At what combined speed were the two cyclists approaching each other?
- Find the distance between the bistro and the playground in km.
(a)
From 12 56 to 13 16 = 20 min
Combined speed of the two cyclists
= 990 ÷ (20 - 10)
= 99 m/min
(b)
Distance between the bistro and the playground
= 20 x 99
= 1980 m
1000 m = 1 km
1980 m = 1.98 km
Distance between the bistro and the playground = 1.98 km
Answer(s): (a) 99 m/min; (b) 1.98 km
