The velocity ( v ) and time ( t ) graph of a body in a straight...

Total distance covered by the body is equal to the modulus of area under graph velocity-time graph

$⇒ d = \left(\dfrac{1}{2} \times 4 \times 2\right) + \left(4 \times 1\right) + \left(\dfrac{1}{2} \times 4 \times \dfrac{4}{3}\right) + \left(\dfrac{1}{2} \times 2 \times \dfrac{5}{3}\right)$

$⇒ d = 4 + 4 + \dfrac{8}{3} + \dfrac{5}{3}$

$⇒ d = \dfrac{37}{3}m$
