At 11 58, Zoe cycled from the bakery towards the grocery store while Lucy cycled from the grocery store towards the bakery. At 12 13, the two cyclists passed each other. 13 minutes later, Zoe reached grocery store but Lucy was 948 m from the bakery.
- At what combined speed were the two cyclists approaching each other?
- Find the distance between the grocery store and the bakery in km.
(a)
From 11 58 to 12 13 = 15 min
Combined speed of the two cyclists
= 948 ÷ (15 - 13)
= 474 m/min
(b)
Distance between the grocery store and the bakery
= 15 x 474
= 7110 m
1000 m = 1 km
7110 m = 7.11 km
Distance between the grocery store and the bakery = 7.11 km
Answer(s): (a) 474 m/min; (b) 7.11 km
