At 11 58, Emily cycled from the market towards the hypermart while Gillian cycled from the hypermart towards the market. At 12 12, the two cyclists passed each other. 7 minutes later, Emily reached hypermart but Gillian was 945 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 11 58 to 12 12 = 14 min
Combined speed of the two cyclists
= 945 ÷ (14 - 7)
= 135 m/min
(b)
Distance between the hypermart and the market
= 14 x 135
= 1890 m
1000 m = 1 km
1890 m = 1.89 km
Distance between the hypermart and the market = 1.89 km
Answer(s): (a) 135 m/min; (b) 1.89 km
