At 13 57, Gem cycled from the market towards the mosque while Winnie cycled from the mosque towards the market. At 14 12, the two cyclists passed each other. 7 minutes later, Gem reached mosque but Winnie was 1168 m from the market.
- At what combined speed were the two cyclists approaching each other?
- Find the distance between the mosque and the market in km.
(a)
From 13 57 to 14 12 = 15 min
Combined speed of the two cyclists
= 1168 ÷ (15 - 7)
= 146 m/min
(b)
Distance between the mosque and the market
= 15 x 146
= 2190 m
1000 m = 1 km
2190 m = 2.19 km
Distance between the mosque and the market = 2.19 km
Answer(s): (a) 146 m/min; (b) 2.19 km
