Final answer:
The scale of the model is 1 inch = 125 feet. The model is 125 times as long as the actual on ramp. The actual on ramp is 0.008 times as long as the model.
Step-by-step explanation:
To find the scale of the model, we need to determine how many inches represent 500 feet. Since the length of the model is 4 inches, we can set up a proportion to solve for the scale:
4 inches / x inches = 500 feet / 1
Cross multiplying gives us:
4x = 500
Dividing both sides by 4 gives us:
x = 125
Therefore, the scale of the model is 1 inch = 125 feet.
To determine how many times as long as the actual on ramp the model is, we can divide the length of the model by the actual length of the on ramp:
4 inches / 500 feet = 1 inch / x
Cross multiplying gives us:
4x = 500
Dividing both sides by 4 gives us:
x = 125
Therefore, the model is 125 times as long as the actual on ramp.
To determine how many times as long as the model the actual on ramp is, we can divide the actual length of the on ramp by the length of the model:
500 feet / 4 inches = x feet / 1 inch
Cross multiplying gives us:
500x = 4
Dividing both sides by 500 gives us:
x = 0.008
Therefore, the actual on ramp is 0.008 times as long as the model.
