At 11 52, Gem cycled from the market towards the grocery store while Jade cycled from the grocery store towards the market. At 12 12, the two cyclists passed each other. 8 minutes later, Gem reached grocery store but Jade was 1152 m from the market.
- At what combined speed were the two cyclists approaching each other?
- Find the distance between the grocery store and the market in km.
(a)
From 11 52 to 12 12 = 20 min
Combined speed of the two cyclists
= 1152 ÷ (20 - 8)
= 96 m/min
(b)
Distance between the grocery store and the market
= 20 x 96
= 1920 m
1000 m = 1 km
1920 m = 1.92 km
Distance between the grocery store and the market = 1.92 km
Answer(s): (a) 96 m/min; (b) 1.92 km
