At 11 57, Opal cycled from the church towards the mosque while Xuan cycled from the mosque towards the church. At 12 15, the two cyclists passed each other. 7 minutes later, Opal reached mosque but Xuan was 990 m from the church.
- At what combined speed were the two cyclists approaching each other?
- Find the distance between the mosque and the church in km.
(a)
From 11 57 to 12 15 = 18 min
Combined speed of the two cyclists
= 990 ÷ (18 - 7)
= 90 m/min
(b)
Distance between the mosque and the church
= 18 x 90
= 1620 m
1000 m = 1 km
1620 m = 1.62 km
Distance between the mosque and the church = 1.62 km
Answer(s): (a) 90 m/min; (b) 1.62 km
