Point 1 is PROBABLY higher up than point 4.
Another possibility is that on the way from Point 1 to point 4,
a lot of people are falling out of the coaster.
We have no way to tell, because you neglected to show us
the picture that goes with this question. It's important.
(C). Remember gravity provides an acceleration of 9.81m/s^2, so the y component of velocity initial is zero because it isn’t already falling, and we have the height, so basically we use the kinematic equation vf^2=vi^2+2ad, substitute given values and you get vf^2=2(9.81)(65) which is 1275, when you take the square root you get 35.7m/s for final velocity
(B). Then you use vf=vi+at to get the equation 35.7=(9.81)t, when you divide out you get 3.64s for time t
(A). Finally, since we assume that there is no acceleration or deceleration horizonatally, we just multiply the time taken for it to hit the ground and the initial speed ((3.64)(35.7)) to get 129.96, with significant figures I would round that to 130 metres.

Walk out, because dense air sinks, cool air rises, so you should have enough air to breathe while walking out, better off, is to hold onto your breath and run out, or put something over your nose and mouth, whichever you use to breathe with, like a mask of some type of cloth. don't forget to stop, duck, and roll if the fires on you.
