the scale model car is 1 inch to 3 1/2ft if a model car is 2 inches long , what is the length in feet of the actual car?
What is 2 times 3 1/2 feet?
2*3.5=?
2 times 3.5 or 3 1/2 is = 7
To solve this problem, we need to use the scale ratio given in the question. The scale ratio states that 1 inch on the model car represents 3 1/2 feet on the actual car.
First, we need to determine the scale factor by converting the measurements to the same unit. There are 12 inches in a foot, so 3 1/2 feet can be converted to (3 * 12 + 1/2) = 42.5 inches.
Now, let's set up a proportion to find the length of the actual car. We can write the proportion as:
1 inch (model car) / 2 inches (actual car) = 3.5 feet (model car) / x feet (actual car)
Using cross-multiplication:
2 inches * 3.5 feet = 1 inch * x feet
7 inches feet = x inches
Since we know that 1 foot is equal to 12 inches, we can divide 7 inches by 12 to convert it to feet:
7 inches / 12 = 0.58 feet
Therefore, the length of the actual car is approximately 0.58 feet.
