we have
The scale factor
That means
1 unit in the model represent 12 units in the actual
1 inch in the model represent 12 inches in the actual
Remember that
so
1 inch in the model represent 1 ft in the actual
The scale factor is
therefore
21 ft in the actual represent 21 inches in the model
Using a system of equations, it is found that Ajay is 25 years old today.
<h3>What is a system of equations?</h3>A system of equations is when two or more variables are related, and equations are built to find the values of each variable.
In this problem, the variables are:
- Variable x: Wale's age.
- Variable y: Ajay's age.
Wale was twice as old as Ajay 10 years back, hence:
Wale will be 40 years old in 10 years, hence:
Then, Ajay's present age is found as follows.
