At 13 54, Olivia cycled from the market towards the hypermart while Victoria cycled from the hypermart towards the market. At 14 14, the two cyclists passed each other. 8 minutes later, Olivia reached hypermart but Victoria was 900 m from the market.
- At what combined speed were the two cyclists approaching each other?
- Find the distance between the hypermart and the market in km.
(a)
From 13 54 to 14 14 = 20 min
Combined speed of the two cyclists
= 900 ÷ (20 - 8)
= 75 m/min
(b)
Distance between the hypermart and the market
= 20 x 75
= 1500 m
1000 m = 1 km
1500 m = 1.5 km
Distance between the hypermart and the market = 1.5 km
Answer(s): (a) 75 m/min; (b) 1.5 km
