At 13 56, Rachel cycled from the school towards the farm while Jane cycled from the farm towards the school. At 14 11, the two cyclists passed each other. 10 minutes later, Rachel reached farm but Jane was 990 m from the school.
- At what combined speed were the two cyclists approaching each other?
- Find the distance between the farm and the school in km.
(a)
From 13 56 to 14 11 = 15 min
Combined speed of the two cyclists
= 990 ÷ (15 - 10)
= 198 m/min
(b)
Distance between the farm and the school
= 15 x 198
= 2970 m
1000 m = 1 km
2970 m = 2.97 km
Distance between the farm and the school = 2.97 km
Answer(s): (a) 198 m/min; (b) 2.97 km
