satellite is 18 meters wide. A model of it was built with a

scale of 1 centimeter : 3 meters. How wide is the model?

To find the width of the model, first calculate the scale factor:

Scale Factor = 1 cm / 3 meters

Next, use this scale factor to calculate the width of the model:

Model Width = Satellite Width / Scale Factor
Model Width = 18 meters / 3
Model Width = 6 meters

Therefore, the model of the satellite is 6 meters wide.
