Question
The velocity V of a vehicle along a straight line is measured in m/s and plotted as shown with respect to time in seconds. At the end of the 7 seconds, how much will the odometer reading increase by (in m)?
Choices
Choice (4)  Response  

a.  5 

b.  3 

c.  4 

d.  0 

Answer
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.
