At 10 57, Marion cycled from the boutique towards the library while Sarah cycled from the library towards the boutique. At 11 17, the two cyclists passed each other. 10 minutes later, Marion reached library but Sarah was 1190 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 10 57 to 11 17 = 20 min
Combined speed of the two cyclists
= 1190 ÷ (20 - 10)
= 119 m/min
(b)
Distance between the library and the boutique
= 20 x 119
= 2380 m
1000 m = 1 km
2380 m = 2.38 km
Distance between the library and the boutique = 2.38 km
Answer(s): (a) 119 m/min; (b) 2.38 km
