At 12 57, Julie cycled from the boutique towards the mosque while Hilda cycled from the mosque towards the boutique. At 13 17, the two cyclists passed each other. 12 minutes later, Julie reached mosque but Hilda was 1136 m from the boutique.
- At what combined speed were the two cyclists approaching each other?
- Find the distance between the mosque and the boutique in km.
(a)
From 12 57 to 13 17 = 20 min
Combined speed of the two cyclists
= 1136 ÷ (20 - 12)
= 142 m/min
(b)
Distance between the mosque and the boutique
= 20 x 142
= 2840 m
1000 m = 1 km
2840 m = 2.84 km
Distance between the mosque and the boutique = 2.84 km
Answer(s): (a) 142 m/min; (b) 2.84 km
