At 10 59, Barbara cycled from the library towards the boutique while Kathy cycled from the boutique towards the library. At 11 14, the two cyclists passed each other. 10 minutes later, Barbara reached boutique but Kathy was 1190 m from the library.
- At what combined speed were the two cyclists approaching each other?
- Find the distance between the boutique and the library in km.
(a)
From 10 59 to 11 14 = 15 min
Combined speed of the two cyclists
= 1190 ÷ (15 - 10)
= 238 m/min
(b)
Distance between the boutique and the library
= 15 x 238
= 3570 m
1000 m = 1 km
3570 m = 3.57 km
Distance between the boutique and the library = 3.57 km
Answer(s): (a) 238 m/min; (b) 3.57 km
