Find Position in Uniform Motion: Car Moving on a Straight Line

[jo3jo3520]

Im just throwing small numbers here so i can get help on the general idea...Im driving a car in uniform motion along a straight line. I go from a position x1=13m at time t1=0 secs to x2=3-m at time t2 = 30 seconds? can anyone help me with the general equation to find the position at different times?

What does uniform motion mean about the speed of your car? Then, what equation in general describes that situation relating position x to speed and time?

If you left city A at 8am and arrived at city B at 11am, and they are 180 miles apart, and you are in uniform motion on the trip...
