What was the question for this implicit rationale, and corresponding answer?
Troy walks to school and back home for a total of 75 x 2 = 150 meters every day. Emily walks to school and back home for a total of 98 x 2 = 196 meters every day. So Emily walks 196 - 150 = 46 meters farther than Troy every day. In five days, Emily walks 46 x 5 = 230 meters farther.
 The answer: 230
The question: Troy's home is 75 meters away from school while Emily's home is 98 meters away from school. Troy and Emily walk to school and back home every day. How much farther does Emily walk to school and back in five days?
