In the velocity-time graph, the distance travelled by the particle between 1.0 sec and 4.0 sec, is approximately

A)  50 m                    

B)         40 m  

C)  30 m                    

D)         20 m

Correct Answer: B

Solution :

 In \[4\] seconds increases in velocity is\[5m/\sec \] Distance travelled between \[1\sec \] and\[4\sec \],\[s=\frac{1}{2}\times 3\times (11.25+15)=\mathbf{40}\,\,\mathbf{m}\]
