At 13 56, Zara cycled from the church towards the library while Abi cycled from the library towards the church. At 14 16, the two cyclists passed each other. 9 minutes later, Zara reached library but Abi was 979 m from the church.
- At what combined speed were the two cyclists approaching each other?
- Find the distance between the library and the church in km.
(a)
From 13 56 to 14 16 = 20 min
Combined speed of the two cyclists
= 979 ÷ (20 - 9)
= 89 m/min
(b)
Distance between the library and the church
= 20 x 89
= 1780 m
1000 m = 1 km
1780 m = 1.78 km
Distance between the library and the church = 1.78 km
Answer(s): (a) 89 m/min; (b) 1.78 km
