At 10 56, Fanny cycled from the mosque towards the grocery store while Tina cycled from the grocery store towards the mosque. At 11 16, the two cyclists passed each other. 15 minutes later, Fanny reached grocery store but Tina was 975 m from the mosque.
- At what combined speed were the two cyclists approaching each other?
- Find the distance between the grocery store and the mosque in km.
(a)
From 10 56 to 11 16 = 20 min
Combined speed of the two cyclists
= 975 ÷ (20 - 15)
= 195 m/min
(b)
Distance between the grocery store and the mosque
= 20 x 195
= 3900 m
1000 m = 1 km
3900 m = 3.9 km
Distance between the grocery store and the mosque = 3.9 km
Answer(s): (a) 195 m/min; (b) 3.9 km
