Astudent sees a newspaper ad for an apartment that has 1930 square feet (ft2) of floor space. how many square meters of area are there?

In order to convert the ft^2 to m^2, we use the multiplier 0.09290304. 
Therefore your calculation would be: 0.09290304 · 1930 = 179.303m^2 (rounded to 3 d.p)

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.
