Answer
a.
Explanation
In a plot of velocity vs time, the distance covered is given by area covered under the graph. Odometer is instrument which records speed.
Since all the square boxes have unit length. Hence, each square is covering 1sq. unit area and half squares are covering 0.5 sq. unit area.
Total area = 0.5 + 1 + 1.5 + 1 + 0.5 + 0.5 = 5 sq. unit area
distance covered is 5m.
