Ok, I need some help on this problem, its related to Robotics:

You have a car that moves some certain number of feet which we know.
How many seconds does it take that car to travel the distance which again we know?

The time depends on the car's velocity, and is an unsolvable problem without that piece of information.

well distance = 1/2 acceleration* t^2 ...

shouldn't be too hard to figure out ... given your acceleration...

You also need to know the initial speed.

...moved this to math and science since it doesn't appear to be about programming (or robotics, for that matter) at all.

I'm accepting nominations for a thread title that makes sense, too. ;)

this is going to based on equations of motion. But, your missing information.

Distance = Initial position + initial velocity x time + 1/2 x acceleration x time^2

Most likely it will be a constant velocity with acceleration and initial position zero, or an acceleration with initial velocity and position zero.

"Equations of motion problem" <---- possible thread title?

To restate the problem, how long will it take for a car to travel a mile?
