I need help with these questions please.

\fBecause Leah's speed is constant her speed at any given instant {her "instantaneous speed'] is also 3 mfs. Plot the data points on the table above on the grid below with time on the horizontal axis and speed on the Medical axis. Label your axes! Draw the line through the points. Calculate the area under the graph {the area between the line and the horizontal axis} after 60 s. Include units! Area=base xner'ght: Aer = The area under a speedvtime graph represents the Can you guess what the slope of a speed-time graph represents? (Hint.- rt's zero in this case in which the velocity is constant.)
