To calculate the height of a child given the number of years since age 2, we can use a linear equation since the child's growth is assumed to be constant over time.
Let's break down the given information:
- The height at age 2 is given as 33 inches.
- The child grows an average of 2.5 inches per year.
Using this information, we can create the equation:
h = 33 + 2.5 * y
Where:
h = height of the child (in inches)
33 = height of the child at age 2 (in inches)
2.5 = average growth rate per year (in inches)
y = number of years since age 2
For example, if we want to calculate the height of a child who is 5 years old:
h = 33 + 2.5 * 5
h = 33 + 12.5
h = 45.5
Therefore, the child would be approximately 45.5 inches tall at age 5.
