Answer:
The value of x = 3.
Step-by-step explanation:
The ratio between length and width is given by:
Where:
- L represents the new length
- W represents the new width
Now, we know that each dimension is reduced by x inches, it means:
Then, we will have:
Finally, we just need to solve it for x.
<u>Therefore, the value of </u><u>x = 3.</u>

What is Distance?
Distance is the total movement of an object without any regard to direction. We can define distance as to how much ground an object has covered despite its starting or ending point.
We are given:
The rate at which two objects drift apart in 1 year = 25 km
To calculate the distance between the two objects in 10 years, we apply unitary method:
The distance, the two objects has drifted apart in 1 year is 25 km
So, the distance, the two objects has been drifted apart in 10 years, will be =
Therefore, the distance between the two objects in 10 years will be 250 kilometers.
