At 10 51, Fiona cycled from the church towards the library while Hazel cycled from the library towards the church. At 11 11, the two cyclists passed each other. 9 minutes later, Fiona reached library but Hazel was 946 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 10 51 to 11 11 = 20 min
Combined speed of the two cyclists
= 946 ÷ (20 - 9)
= 86 m/min
(b)
Distance between the library and the church
= 20 x 86
= 1720 m
1000 m = 1 km
1720 m = 1.72 km
Distance between the library and the church = 1.72 km
Answer(s): (a) 86 m/min; (b) 1.72 km
