At 12 58, Jane cycled from the mall towards the grocery store while Risa cycled from the grocery store towards the mall. At 13 11, the two cyclists passed each other. 8 minutes later, Jane reached grocery store but Risa was 1150 m from the mall.
- At what combined speed were the two cyclists approaching each other?
- Find the distance between the grocery store and the mall in km.
(a)
From 12 58 to 13 11 = 13 min
Combined speed of the two cyclists
= 1150 ÷ (13 - 8)
= 230 m/min
(b)
Distance between the grocery store and the mall
= 13 x 230
= 2990 m
1000 m = 1 km
2990 m = 2.99 km
Distance between the grocery store and the mall = 2.99 km
Answer(s): (a) 230 m/min; (b) 2.99 km
