At 10 52, Gabby cycled from the park towards the hypermart while Elyse cycled from the hypermart towards the park. At 11 12, the two cyclists passed each other. 10 minutes later, Gabby reached hypermart but Elyse was 1200 m from the park.
- At what combined speed were the two cyclists approaching each other?
- Find the distance between the hypermart and the park in km.
(a)
From 10 52 to 11 12 = 20 min
Combined speed of the two cyclists
= 1200 ÷ (20 - 10)
= 120 m/min
(b)
Distance between the hypermart and the park
= 20 x 120
= 2400 m
1000 m = 1 km
2400 m = 2.4 km
Distance between the hypermart and the park = 2.4 km
Answer(s): (a) 120 m/min; (b) 2.4 km
