At 12 55, Betty cycled from the hypermart towards the salon while Olivia cycled from the salon towards the hypermart. At 13 12, the two cyclists passed each other. 12 minutes later, Betty reached salon but Olivia was 950 m from the hypermart.
- At what combined speed were the two cyclists approaching each other?
- Find the distance between the salon and the hypermart in km.
(a)
From 12 55 to 13 12 = 17 min
Combined speed of the two cyclists
= 950 ÷ (17 - 12)
= 190 m/min
(b)
Distance between the salon and the hypermart
= 17 x 190
= 3230 m
1000 m = 1 km
3230 m = 3.23 km
Distance between the salon and the hypermart = 3.23 km
Answer(s): (a) 190 m/min; (b) 3.23 km
