At 12 58, Olivia cycled from the market towards the mosque while Barbara cycled from the mosque towards the market. At 13 13, the two cyclists passed each other. 12 minutes later, Olivia reached mosque but Barbara was 918 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 12 58 to 13 13 = 15 min
Combined speed of the two cyclists
= 918 ÷ (15 - 12)
= 306 m/min
(b)
Distance between the mosque and the market
= 15 x 306
= 4590 m
1000 m = 1 km
4590 m = 4.59 km
Distance between the mosque and the market = 4.59 km
Answer(s): (a) 306 m/min; (b) 4.59 km
