a pick up truck is 13 feet in length. tioanna wants to make a scale model of the truck using a scale of the 1 inch = 2 feet. what will be the length of the model truck?
An easy way to solve this problem is with a proportion. 1 is to 2 as x is to 13.
1/2 = x/13
Cross multiply:
2x = 13
x = 13/2
x = 6.5 inches
i got 6 1/2
You're right.
6.5 = 6 1/2

To find the length of the model truck, we need to use the given scale of 1 inch = 2 feet. Here's how you can calculate it:
1. Start by determining the length of the model truck in inches:
- Given that the pick-up truck is 13 feet long.
- Since the scale is 1 inch = 2 feet, we can write the conversion as:
- 1 inch = 2 feet
- Multiply both sides of the equation by 13:
- 1 inch * 13 = 2 feet * 13
- 13 inches = 26 feet
2. So, the length of the model truck is 13 inches.
Therefore, the length of the model truck will be 13 inches.
