At 11 52, Joelle cycled from the library towards the market while Gem cycled from the market towards the library. At 12 11, the two cyclists passed each other. 10 minutes later, Joelle reached market but Gem was 1170 m from the library.
- At what combined speed were the two cyclists approaching each other?
- Find the distance between the market and the library in km.
(a)
From 11 52 to 12 11 = 19 min
Combined speed of the two cyclists
= 1170 ÷ (19 - 10)
= 130 m/min
(b)
Distance between the market and the library
= 19 x 130
= 2470 m
1000 m = 1 km
2470 m = 2.47 km
Distance between the market and the library = 2.47 km
Answer(s): (a) 130 m/min; (b) 2.47 km
