At 11 51, Sabrina cycled from the library towards the salon while Dana cycled from the salon towards the library. At 12 11, the two cyclists passed each other. 15 minutes later, Sabrina reached salon but Dana was 1015 m from the library.
- At what combined speed were the two cyclists approaching each other?
- Find the distance between the salon and the library in km.
(a)
From 11 51 to 12 11 = 20 min
Combined speed of the two cyclists
= 1015 ÷ (20 - 15)
= 203 m/min
(b)
Distance between the salon and the library
= 20 x 203
= 4060 m
1000 m = 1 km
4060 m = 4.06 km
Distance between the salon and the library = 4.06 km
Answer(s): (a) 203 m/min; (b) 4.06 km
