The motion of an airplane is represented by velocity-time graph as shown below. The distance covered by airplane in the first 30.5 second is _______ km.
$12$
$3$
$6$
$9$
Solution
Distance = area under the graph $\begin{aligned} d & =300 \times 2+400 \times 28.5 \\
& =600+114000 \\
& =12000 \mathrm{~m} \end{aligned}$
