The distance between flaws on a long cable is exponentially distributed with mean 12 m. a.) Find the probability that the distance between two flaws is 15 m. b.) Find the probability that the distance between two flaws is between 8 and 20 m. c.) Find the median distance between flaws.

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.
