Question

A cab driver drove west 2.4 miles. He then drove 6.83 miles east. How far and in which direction did he end up from his starting point? Use - (negative) to indicate west and + (positive) to indicate east.
A: +4.43
B: -4.43
C: +9.23
D: -9.23

the answer is A:+4.43

Step-by-step explanation:

Answer 2

Because the cab driver drove west and then east, it must be east for the direction he ends up in. We then see that the answer is A because the west is negative so you subtract from the number of miles he drove east, instead of adding. So, once again, the answer is A:+4.43
