At 13 59, Xylia cycled from the market towards the grocery store while Yoko cycled from the grocery store towards the market. At 14 19, the two cyclists passed each other. 15 minutes later, Xylia reached grocery store but Yoko was 1150 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 13 59 to 14 19 = 20 min
Combined speed of the two cyclists
= 1150 ÷ (20 - 15)
= 230 m/min
(b)
Distance between the grocery store and the market
= 20 x 230
= 4600 m
1000 m = 1 km
4600 m = 4.6 km
Distance between the grocery store and the market = 4.6 km
Answer(s): (a) 230 m/min; (b) 4.6 km
