Final answer:
The length of the scale model of the Sydney Harbour Bridge, which is based on a scale of 1:6000, is 0.2 metres or 20 centimetres.
Step-by-step explanation:
The question asks us to determine the length of a scale model of the Sydney Harbour Bridge. Given that the Sydney Harbour Bridge is approximately 1200 metres long and the scale of the model is 1:6000, we calculate the length of the model by dividing the actual length by the scale factor.
To find the model length, divide the actual length of the bridge by the scale factor:
Model length = Actual length / Scale factor
Model length = 1200 metres / 6000
Model length = 0.2 metres, which is the same as 20 centimetres.
This calculation indicates that the model will be 20 centimetres in length.
