At 11 58, Jane cycled from the library towards the bank while Barbara cycled from the bank towards the library. At 12 13, the two cyclists passed each other. 13 minutes later, Jane reached bank but Barbara was 1072 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 11 58 to 12 13 = 15 min
Combined speed of the two cyclists
= 1072 ÷ (15 - 13)
= 536 m/min
(b)
Distance between the bank and the library
= 15 x 536
= 8040 m
1000 m = 1 km
8040 m = 8.04 km
Distance between the bank and the library = 8.04 km
Answer(s): (a) 536 m/min; (b) 8.04 km
