Final answer:
The length of the actual car modeled after the scale model is 195.20 inches.
Step-by-step explanation:
To find the length of the actual car, we need to use the scale ratio and the length of the model car. The scale is given as 2 : 128, which means that the model car is 2 units long for every 128 units of the actual car. Since the model car is 3.05 inches long, we can set up the following proportion:
2 units / 128 units = 3.05 inches / x inches
Cross-multiplying, we get 2x = (3.05)(128),
x = (3.05)(128) / 2 = 195.2 inches.
Therefore, the length of the actual car it’s modeled after is 195.20 inches (D).
