At 13 57, Lucy cycled from the mosque towards the grocery store while Lynn cycled from the grocery store towards the mosque. At 14 17, the two cyclists passed each other. 15 minutes later, Lucy reached grocery store but Lynn was 905 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 13 57 to 14 17 = 20 min
Combined speed of the two cyclists
= 905 ÷ (20 - 15)
= 181 m/min
(b)
Distance between the grocery store and the mosque
= 20 x 181
= 3620 m
1000 m = 1 km
3620 m = 3.62 km
Distance between the grocery store and the mosque = 3.62 km
Answer(s): (a) 181 m/min; (b) 3.62 km
