At 11 57, Shannon cycled from the library towards the playground while Hazel cycled from the playground towards the library. At 12 17, the two cyclists passed each other. 13 minutes later, Shannon reached playground but Hazel was 1176 m from the library.
- At what combined speed were the two cyclists approaching each other?
- Find the distance between the playground and the library in km.
(a)
From 11 57 to 12 17 = 20 min
Combined speed of the two cyclists
= 1176 ÷ (20 - 13)
= 168 m/min
(b)
Distance between the playground and the library
= 20 x 168
= 3360 m
1000 m = 1 km
3360 m = 3.36 km
Distance between the playground and the library = 3.36 km
Answer(s): (a) 168 m/min; (b) 3.36 km
