At 10 56, Marion cycled from the clinic towards the salon while Xuan cycled from the salon towards the clinic. At 11 14, the two cyclists passed each other. 15 minutes later, Marion reached salon but Xuan was 1185 m from the clinic.
- At what combined speed were the two cyclists approaching each other?
- Find the distance between the salon and the clinic in km.
(a)
From 10 56 to 11 14 = 18 min
Combined speed of the two cyclists
= 1185 ÷ (18 - 15)
= 395 m/min
(b)
Distance between the salon and the clinic
= 18 x 395
= 7110 m
1000 m = 1 km
7110 m = 7.11 km
Distance between the salon and the clinic = 7.11 km
Answer(s): (a) 395 m/min; (b) 7.11 km
