At 10 58, Roshel cycled from the grocery store towards the cinema while Kimberly cycled from the cinema towards the grocery store. At 11 18, the two cyclists passed each other. 8 minutes later, Roshel reached cinema but Kimberly was 1140 m from the grocery store.
- At what combined speed were the two cyclists approaching each other?
- Find the distance between the cinema and the grocery store in km.
(a)
From 10 58 to 11 18 = 20 min
Combined speed of the two cyclists
= 1140 ÷ (20 - 8)
= 95 m/min
(b)
Distance between the cinema and the grocery store
= 20 x 95
= 1900 m
1000 m = 1 km
1900 m = 1.9 km
Distance between the cinema and the grocery store = 1.9 km
Answer(s): (a) 95 m/min; (b) 1.9 km
