At 11 53, Jade cycled from the library towards the grocery store while Anna cycled from the grocery store towards the library. At 12 13, the two cyclists passed each other. 12 minutes later, Jade reached grocery store but Anna was 944 m from the library.
- At what combined speed were the two cyclists approaching each other?
- Find the distance between the grocery store and the library in km.
(a)
From 11 53 to 12 13 = 20 min
Combined speed of the two cyclists
= 944 ÷ (20 - 12)
= 118 m/min
(b)
Distance between the grocery store and the library
= 20 x 118
= 2360 m
1000 m = 1 km
2360 m = 2.36 km
Distance between the grocery store and the library = 2.36 km
Answer(s): (a) 118 m/min; (b) 2.36 km
