A runner starts at a position of 5.0 m and travels at a rate of -3.2 m/s. Determine the time, in seconds, when the runner will reach a position of -17 m.

Divide 108.2 x 10^6 into 1.5 x 10 and the result will be in au (astronomical units)

You need to be more specific.  i really don't know what a "motion map" is.you can draw a graph of an object's position, distance, displacement, speed,velocity, or acceleration versus time, or you can draw a graph of the object's x-position versus its y-position and not give any information about time at all.if the graph presents position or displacement against time,  then constant velocity is a straight line . . i.e. a line that has  constant slope.if the graph shows speed against time, then constant velocityis a horizontal piece of line.if the graph shows acceleration against time, then constant  velocity is a piece of line that lies on the x-axis . . it's value is zero.
