Slope is for a average rate and unit rate is what you get for just one thing
Since ur using r as a variable the answer is r = 7.
U could answer that question by adding 2.45+1.9=4.35
Here you have to use proportionality,
1 feet is 12 inches so 40 feets is 480 inches
Then the real locomotive is 480/16=30 times wider then the model
And then a window on the real locomotive is 30 times wider then the model..
Step-by-step explanation:
hereee is your answerr
hope it helps
