At 13 57, Ivory cycled from the bank towards the playground while Barbara cycled from the playground towards the bank. At 14 12, the two cyclists passed each other. 11 minutes later, Ivory reached playground but Barbara was 1040 m from the bank.
- At what combined speed were the two cyclists approaching each other?
- Find the distance between the playground and the bank in km.
(a)
From 13 57 to 14 12 = 15 min
Combined speed of the two cyclists
= 1040 ÷ (15 - 11)
= 260 m/min
(b)
Distance between the playground and the bank
= 15 x 260
= 3900 m
1000 m = 1 km
3900 m = 3.9 km
Distance between the playground and the bank = 3.9 km
Answer(s): (a) 260 m/min; (b) 3.9 km
