Question

In the given $v$-$t$ graph the distance travelled by the body in $5$ seconds will be

• A. $100m$
• B. $80m$
• C. $40m$
• D. $20m$

Answer 1

Answer: (A)

The distance is equal to total area under $v$-$t$ graph
$=\frac{20\times 2}{2}+20\times 2+20\times 1+\frac{20\times 1}{2}+\frac{20\times 1}{2}$
$=100m$
