Answer:

The length of the actual tractor is:

  • 56 feet.

Step-by-step explanation:

Firstly, you must know the conversión between inches and feet:

  • 1 foot = 12 inches

Or

  • 1 inch = 0.0833333 feet

How the paragraph says that the scale is 1 to 64, it means by each unit in the scale, the unit in the actual tractor is 64 times bigger, so, you must multiply the measure of the model by 64 to obtain the actual length in inches:

  • Length of the actual tractor = 10.5 inches * 64 = 672 inches

The paragraph says the length must be in feet, so we must apply the conversion given above in a simple rule of three how I'll show below:

  • 1 foot = 12 inches
  • x = 672 inches

And we operate:

  • x = (672 inches * 1 foot) / 12 inches

After we cancel the unit "inches:"

  • x = 672 feet / 12
  • x = 56 feet

For this reason, we obtain the final value of 56 feet to the actual length of the tractor.
