At 11 56, Raeann cycled from the library towards the bistro while Natalie cycled from the bistro towards the library. At 12 16, the two cyclists passed each other. 9 minutes later, Raeann reached bistro but Natalie was 935 m from the library.
- At what combined speed were the two cyclists approaching each other?
- Find the distance between the bistro and the library in km.
(a)
From 11 56 to 12 16 = 20 min
Combined speed of the two cyclists
= 935 ÷ (20 - 9)
= 85 m/min
(b)
Distance between the bistro and the library
= 20 x 85
= 1700 m
1000 m = 1 km
1700 m = 1.7 km
Distance between the bistro and the library = 1.7 km
Answer(s): (a) 85 m/min; (b) 1.7 km
