Answer:

The sear tower is
times higher than the sears tower model
Step-by-step explanation:
we know that
The ratio of the height of the model to the height of the actual sears tower is equal to the scale factor
Let
z------> the scale factor
x-------> the height of the model
y-------> the height of the actual
so

we have


substitute

simplify

Remember that

so

The distance depends on the time.
So now we need to find the constant of variation or the constant of proportionality.
To do so we must find y(the dependent variable) and x(the independent variable).
To find the constant(k) we must find y/x
Since y/x=k
Then 2.25/.75=k
k=3
