प्रश्न
The figure represents graphically the velocity of a car moving along a straight road over a period of 100 hours.
Calculate the distance travelled in the last 40 h.
उत्तर
Distance travelled in last 40 hour would be equal to area under graph during that time = 50 x (100 - 60) + `1/2`x(100 - 60) x(100 - 50).
S = 2000 + 1000 = 3000 km.
