Question

Figure represents the speed-time graph for a particle. Find the distance covered by the particle between $t=10min$ and $t=30min$

Answer 1

Area under the s-t graph will give the distance. The distance covered is equal to the area of the rectangle ABCD. Its value is $ABCD=(30min-10min)\times 10km/hr)$
$=20min\times 10km/hr$
$=\frac{20}{60}hr\times 10km/hr=\frac{10}{3}km$
