At 10 55, Gwen cycled from the florist towards the playground while Usha cycled from the playground towards the florist. At 11 15, the two cyclists passed each other. 7 minutes later, Gwen reached playground but Usha was 910 m from the florist.
- At what combined speed were the two cyclists approaching each other?
- Find the distance between the playground and the florist in km.
(a)
From 10 55 to 11 15 = 20 min
Combined speed of the two cyclists
= 910 ÷ (20 - 7)
= 70 m/min
(b)
Distance between the playground and the florist
= 20 x 70
= 1400 m
1000 m = 1 km
1400 m = 1.4 km
Distance between the playground and the florist = 1.4 km
Answer(s): (a) 70 m/min; (b) 1.4 km
