Answer:
The required equation is and the required model is shown in figure 1.
Step-by-step explanation:
Consider the provided information.
We need to draw a model and write an equation to represent 4 times as many as 3 is 12.
4 times as many as 3 can be written as:
This expression is equal to 12. Thus the combined equation is:
The required model is shown in figure 1:
64
b=9
divide by 3 on both sides to get the variable (b) by itself
Answer:12 miles per hour
