One end of an insulated metal rod is maintained at 100 ∘c and the other end is maintained at 0.00 ∘c by ice–water mixture. the rod has a length of 60.0 cm and a cross-sectional area of 1.50 cm2. the heat conducted by the rod melts a mass of 8.30 g of ice in a time of 10.0 min. find the thermal conductivity k of the metal.

Where are the options ?

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.
