At 12 54, Lucy cycled from the park towards the hypermart while Eva cycled from the hypermart towards the park. At 13 11, the two cyclists passed each other. 9 minutes later, Lucy reached hypermart but Eva was 960 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 12 54 to 13 11 = 17 min
Combined speed of the two cyclists
= 960 ÷ (17 - 9)
= 120 m/min
(b)
Distance between the hypermart and the park
= 17 x 120
= 2040 m
1000 m = 1 km
2040 m = 2.04 km
Distance between the hypermart and the park = 2.04 km
Answer(s): (a) 120 m/min; (b) 2.04 km
