At 13 58, Jaslyn cycled from the bank towards the hypermart while Betty cycled from the hypermart towards the bank. At 14 11, the two cyclists passed each other. 10 minutes later, Jaslyn reached hypermart but Betty was 1200 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 58 to 14 11 = 13 min
Combined speed of the two cyclists
= 1200 ÷ (13 - 10)
= 400 m/min
(b)
Distance between the hypermart and the bank
= 13 x 400
= 5200 m
1000 m = 1 km
5200 m = 5.2 km
Distance between the hypermart and the bank = 5.2 km
Answer(s): (a) 400 m/min; (b) 5.2 km
