At 10 53, Emily cycled from the farm towards the library while Barbara cycled from the library towards the farm. At 11 13, the two cyclists passed each other. 10 minutes later, Emily reached library but Barbara was 1150 m from the farm.
- At what combined speed were the two cyclists approaching each other?
- Find the distance between the library and the farm in km.
(a)
From 10 53 to 11 13 = 20 min
Combined speed of the two cyclists
= 1150 ÷ (20 - 10)
= 115 m/min
(b)
Distance between the library and the farm
= 20 x 115
= 2300 m
1000 m = 1 km
2300 m = 2.3 km
Distance between the library and the farm = 2.3 km
Answer(s): (a) 115 m/min; (b) 2.3 km
