At 13 54, Kathy cycled from the bakery towards the bank while Barbara cycled from the bank towards the bakery. At 14 14, the two cyclists passed each other. 12 minutes later, Kathy reached bank but Barbara was 904 m from the bakery.
- At what combined speed were the two cyclists approaching each other?
- Find the distance between the bank and the bakery in km.
(a)
From 13 54 to 14 14 = 20 min
Combined speed of the two cyclists
= 904 ÷ (20 - 12)
= 113 m/min
(b)
Distance between the bank and the bakery
= 20 x 113
= 2260 m
1000 m = 1 km
2260 m = 2.26 km
Distance between the bank and the bakery = 2.26 km
Answer(s): (a) 113 m/min; (b) 2.26 km
