At 12 57, Gabby cycled from the church towards the mosque while Emma cycled from the mosque towards the church. At 13 15, the two cyclists passed each other. 12 minutes later, Gabby reached mosque but Emma was 1020 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 12 57 to 13 15 = 18 min
Combined speed of the two cyclists
= 1020 ÷ (18 - 12)
= 170 m/min
(b)
Distance between the mosque and the church
= 18 x 170
= 3060 m
1000 m = 1 km
3060 m = 3.06 km
Distance between the mosque and the church = 3.06 km
Answer(s): (a) 170 m/min; (b) 3.06 km
