At 11 58, Min cycled from the hypermart towards the market while Lucy cycled from the market towards the hypermart. At 12 13, the two cyclists passed each other. 9 minutes later, Min reached market but Lucy was 1080 m from the hypermart.
- At what combined speed were the two cyclists approaching each other?
- Find the distance between the market and the hypermart in km.
(a)
From 11 58 to 12 13 = 15 min
Combined speed of the two cyclists
= 1080 ÷ (15 - 9)
= 180 m/min
(b)
Distance between the market and the hypermart
= 15 x 180
= 2700 m
1000 m = 1 km
2700 m = 2.7 km
Distance between the market and the hypermart = 2.7 km
Answer(s): (a) 180 m/min; (b) 2.7 km
