Neither cause there both at the same constant rate so one train wouldn’t be traveling at a greater speed unless there is something missing from the question being asked like the actual speed of each individual train then there would be one train traveling at a greater speed
The answer will be z=-6 because 16-8=6
60-14 , 25x46=1150. Thats how you solve it
Let f(x)=0, you'll get x=3 and x=-5, those are the x-intercepts of the function.
