a) How long does it take the driver to complete the pass?

b) If x1 is the position of the driver, and x2 is the position of the oncoming car, what would be the value of separation distance (x2 - x1) at the end of a successful pass?

c) What would be the driver's speed at the end of the pass?

I am not sure what equations to use?

So, he has to go 44 m further than the truck in the same time. He has to do this before the car meets them.

900m= 25t + 23t +1/2 2.2 t^2

solve for t. check that.

I solved for the quadratic and calculated 14.157 seconds. This assignment is on-line, so I get instant feedback and was told that this answer was incorrect. Any explanation? Thank you so much for the help.
