to get to a dog show, mr luna first drives 7 miles west from his home and then 3 miles north. next he turns east and drives 11 miles. finally he turns north and drives 4 miles to the dog show. how far north of mr. luna's home is the dog show?
Mr. Luna's travels east and west are irrelevant to the question. He drives 3 miles north, then he drives 4 more miles north. 3 + 4 = 7, so Mr. Luna ends up 7 miles north of his home.
