Solution 6.1
From Mechanics
The area under the velocity-time graph gives the distance travelled.
This area can be calculated either by breaking up the area into three parts, two triangles and a rectangle
or by using the formula for the area of a trapedium as the graph in the figure defines a trapezium with the
This latter method gives
