At 13 55, Betty cycled from the cinema towards the grocery store while Raeann cycled from the grocery store towards the cinema. At 14 15, the two cyclists passed each other. 11 minutes later, Betty reached grocery store but Raeann was 1053 m from the cinema.
- At what combined speed were the two cyclists approaching each other?
- Find the distance between the grocery store and the cinema in km.
(a)
From 13 55 to 14 15 = 20 min
Combined speed of the two cyclists
= 1053 ÷ (20 - 11)
= 117 m/min
(b)
Distance between the grocery store and the cinema
= 20 x 117
= 2340 m
1000 m = 1 km
2340 m = 2.34 km
Distance between the grocery store and the cinema = 2.34 km
Answer(s): (a) 117 m/min; (b) 2.34 km
