At 11 58, Yoko cycled from the library towards the bistro while Natalie cycled from the bistro towards the library. At 12 13, the two cyclists passed each other. 10 minutes later, Yoko reached bistro but Natalie was 1040 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 58 to 12 13 = 15 min
Combined speed of the two cyclists
= 1040 ÷ (15 - 10)
= 208 m/min
(b)
Distance between the bistro and the library
= 15 x 208
= 3120 m
1000 m = 1 km
3120 m = 3.12 km
Distance between the bistro and the library = 3.12 km
Answer(s): (a) 208 m/min; (b) 3.12 km
