At 10 57, Risa cycled from the library towards the museum while Joelle cycled from the museum towards the library. At 11 17, the two cyclists passed each other. 12 minutes later, Risa reached museum but Joelle was 912 m from the library.
- At what combined speed were the two cyclists approaching each other?
- Find the distance between the museum and the library in km.
(a)
From 10 57 to 11 17 = 20 min
Combined speed of the two cyclists
= 912 ÷ (20 - 12)
= 114 m/min
(b)
Distance between the museum and the library
= 20 x 114
= 2280 m
1000 m = 1 km
2280 m = 2.28 km
Distance between the museum and the library = 2.28 km
Answer(s): (a) 114 m/min; (b) 2.28 km
