1) Two trains start from Fort Worth traveling at the same speed. The trip for Train \( W \) takes \( 20 \) hours, while the trip for Train \( Z \) takes \( 25 \) hours. If the city Train \( Z \) is traveling to is \( 400 \) miles farther away than the city Train \( W \) is traveling to, how far will each train travel in total to reach its destination? 

Which of the following rational equations best models this situation? 

\(\frac { x } { 20 } = \frac { x + 400 } { 25 } \) 

\( \frac { x } { 20 } = \frac { x - 400 } { 25 } \) 

\( \frac { x } { 25 } = \frac { x + 400 } { 20 } \) 

\( \frac { x } { 20 } = \frac { x } { 25 } - 400 \) 

\( \frac { x } { 20 } + 400 = \frac { x } { 25 }\) 

Answer

\(\frac { x } { 20 } = \frac { x + 400 } { 25 }\)
