At 10 54, Winnie cycled from the cafe towards the bakery while Lucy cycled from the bakery towards the cafe. At 11 11, the two cyclists passed each other. 15 minutes later, Winnie reached bakery but Lucy was 1200 m from the cafe.
- At what combined speed were the two cyclists approaching each other?
- Find the distance between the bakery and the cafe in km.
(a)
From 10 54 to 11 11 = 17 min
Combined speed of the two cyclists
= 1200 ÷ (17 - 15)
= 600 m/min
(b)
Distance between the bakery and the cafe
= 17 x 600
= 10200 m
1000 m = 1 km
10200 m = 10.2 km
Distance between the bakery and the cafe = 10.2 km
Answer(s): (a) 600 m/min; (b) 10.2 km
