At 10 58, Diana cycled from the library towards the bank while Xylia cycled from the bank towards the library. At 11 13, the two cyclists passed each other. 11 minutes later, Diana reached bank but Xylia was 1200 m from the library.
- At what combined speed were the two cyclists approaching each other?
- Find the distance between the bank and the library in km.
(a)
From 10 58 to 11 13 = 15 min
Combined speed of the two cyclists
= 1200 ÷ (15 - 11)
= 300 m/min
(b)
Distance between the bank and the library
= 15 x 300
= 4500 m
1000 m = 1 km
4500 m = 4.5 km
Distance between the bank and the library = 4.5 km
Answer(s): (a) 300 m/min; (b) 4.5 km
