Answer: (-2y+3)(y+11)

Step-by-step explanation:

33 is 3×11 so expect something like

(y+3)(y+11) = y^2+14y+33

leading term has coefficient -2 so

one factor is like (-2y+__)

Try (-2y+3)(y+11) = -2y^2-19y+33

which happens to be the answer

Since the first train has been travelling for 3 hours, we have the following equations:
$d=50t+3*50=50t+150$
$d=60t$

We want to know when they will be equal, so set these equal to eachother:
$60t=50t+150$
$10t=150$
$t=15$

So 15 hours after the second train leaves, they will be at the same distance. This is at 8AM since the second train leaves at 5PM.
