At 12 53, Olivia cycled from the clinic towards the library while Nora cycled from the library towards the clinic. At 13 11, the two cyclists passed each other. 15 minutes later, Olivia reached library but Nora was 1035 m from the clinic.
- At what combined speed were the two cyclists approaching each other?
- Find the distance between the library and the clinic in km.
(a)
From 12 53 to 13 11 = 18 min
Combined speed of the two cyclists
= 1035 ÷ (18 - 15)
= 345 m/min
(b)
Distance between the library and the clinic
= 18 x 345
= 6210 m
1000 m = 1 km
6210 m = 6.21 km
Distance between the library and the clinic = 6.21 km
Answer(s): (a) 345 m/min; (b) 6.21 km
