At 10 54, Marion cycled from the clinic towards the farm while Julie cycled from the farm towards the clinic. At 11 12, the two cyclists passed each other. 9 minutes later, Marion reached farm but Julie was 1125 m from the clinic.
- At what combined speed were the two cyclists approaching each other?
- Find the distance between the farm and the clinic in km.
(a)
From 10 54 to 11 12 = 18 min
Combined speed of the two cyclists
= 1125 ÷ (18 - 9)
= 125 m/min
(b)
Distance between the farm and the clinic
= 18 x 125
= 2250 m
1000 m = 1 km
2250 m = 2.25 km
Distance between the farm and the clinic = 2.25 km
Answer(s): (a) 125 m/min; (b) 2.25 km
