Question

Find the distance covered by a particle during the interval $t=0$ to $t=20$ s for which the speed-time graph is shown in figure.

• A. 200 m
• B. 400 m
• C. 100 m
• D. 300 m

Answer 1

The correct option is A 200 m

Area under the speed-time graph gives the distance.
The distance covered in the time interval 0 to 20 s is equal to the area of the shaded triangle.
$Area=\frac{1}{2}\times base\times height$
$=\frac{1}{2}\times \left(20s\right)\times \left(20m/s\right)$
$=200m$
