Kirsten's house is located at a point on the map that is 7 miles west and 2 miles south of the center of town. She drives to a movie
theater, which is 5 miles east and 3 miles north of the center of town. If
the image represents the road she drove, how far did she travel?

Kirsten had to drive 5 miles north, and then turn to the east for 12 miles where she found a nice parking spot at the Movie Theater :)

If the image represents the road she drove, she did travel 5 + 12 miles, thus she finally travelled 17 miles.

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.

168

step-by-step explanation:

first off, we know that he drove 3.5 hours at a rate of 48 mph.

knowing that, we want to see how many miles he drove all-together.

in this case, we can just multiply 48 by 3.5.

48 * 3.5 = 168
