At 10 57, Zara cycled from the library towards the bistro while Tiffany cycled from the bistro towards the library. At 11 15, the two cyclists passed each other. 14 minutes later, Zara reached bistro but Tiffany was 940 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 10 57 to 11 15 = 18 min
Combined speed of the two cyclists
= 940 ÷ (18 - 14)
= 235 m/min
(b)
Distance between the bistro and the library
= 18 x 235
= 4230 m
1000 m = 1 km
4230 m = 4.23 km
Distance between the bistro and the library = 4.23 km
Answer(s): (a) 235 m/min; (b) 4.23 km
