At 13 55, Joelle cycled from the church towards the school while Lynn cycled from the school towards the church. At 14 15, the two cyclists passed each other. 7 minutes later, Joelle reached school but Lynn was 1170 m from the church.
- At what combined speed were the two cyclists approaching each other?
- Find the distance between the school and the church in km.
(a)
From 13 55 to 14 15 = 20 min
Combined speed of the two cyclists
= 1170 ÷ (20 - 7)
= 90 m/min
(b)
Distance between the school and the church
= 20 x 90
= 1800 m
1000 m = 1 km
1800 m = 1.8 km
Distance between the school and the church = 1.8 km
Answer(s): (a) 90 m/min; (b) 1.8 km
