At 13 53, Anna cycled from the bank towards the hypermart while Hilda cycled from the hypermart towards the bank. At 14 13, the two cyclists passed each other. 13 minutes later, Anna reached hypermart but Hilda was 1120 m from the bank.
- At what combined speed were the two cyclists approaching each other?
- Find the distance between the hypermart and the bank in km.
(a)
From 13 53 to 14 13 = 20 min
Combined speed of the two cyclists
= 1120 ÷ (20 - 13)
= 160 m/min
(b)
Distance between the hypermart and the bank
= 20 x 160
= 3200 m
1000 m = 1 km
3200 m = 3.2 km
Distance between the hypermart and the bank = 3.2 km
Answer(s): (a) 160 m/min; (b) 3.2 km
