It looks like you're just going to add everything up...
1,008 +1,547+ 2897 + 265,489 + .07(265,489) = $289,525.20
None of these are correct. the answer is 6 hours, because if the the train is traveling at 30m/h and the distance = 180m than your equation is 30m/180
The correct answer is: -2x > 6!
-2x > 6
-2x / -2 > 6 / -2
x > -3
