At 12 59, Cathy cycled from the playground towards the museum while Xuan cycled from the museum towards the playground. At 13 16, the two cyclists passed each other. 13 minutes later, Cathy reached museum but Xuan was 920 m from the playground.
- At what combined speed were the two cyclists approaching each other?
- Find the distance between the museum and the playground in km.
(a)
From 12 59 to 13 16 = 17 min
Combined speed of the two cyclists
= 920 ÷ (17 - 13)
= 230 m/min
(b)
Distance between the museum and the playground
= 17 x 230
= 3910 m
1000 m = 1 km
3910 m = 3.91 km
Distance between the museum and the playground = 3.91 km
Answer(s): (a) 230 m/min; (b) 3.91 km
