At 12 51, Nicole cycled from the mall towards the salon while Irene cycled from the salon towards the mall. At 13 11, the two cyclists passed each other. 12 minutes later, Nicole reached salon but Irene was 1008 m from the mall.
- At what combined speed were the two cyclists approaching each other?
- Find the distance between the salon and the mall in km.
(a)
From 12 51 to 13 11 = 20 min
Combined speed of the two cyclists
= 1008 ÷ (20 - 12)
= 126 m/min
(b)
Distance between the salon and the mall
= 20 x 126
= 2520 m
1000 m = 1 km
2520 m = 2.52 km
Distance between the salon and the mall = 2.52 km
Answer(s): (a) 126 m/min; (b) 2.52 km
