At 12 54, Penelope cycled from the boutique towards the library while Shannon cycled from the library towards the boutique. At 13 12, the two cyclists passed each other. 12 minutes later, Penelope reached library but Shannon was 930 m from the boutique.
- At what combined speed were the two cyclists approaching each other?
- Find the distance between the library and the boutique in km.
(a)
From 12 54 to 13 12 = 18 min
Combined speed of the two cyclists
= 930 ÷ (18 - 12)
= 155 m/min
(b)
Distance between the library and the boutique
= 18 x 155
= 2790 m
1000 m = 1 km
2790 m = 2.79 km
Distance between the library and the boutique = 2.79 km
Answer(s): (a) 155 m/min; (b) 2.79 km
