Question

Below Figure represents the speed time graph for a particle. Find the distance covered by the particle between $t=2\text{Min}$ to $t=6\text{Min}$.

• A. $5\text{Km}$
• B. $4.8\text{Km}$
• C. $4\text{Km}$
• D. $5.2\text{Km}$

Answer 1

The correct option is B $4.8\text{Km}$

Given speed-time curve as

As per the given curve, speed is constant for the given time interval which is $20\text{m/s}$
Time, $\Delta t=6-2=4\text{Min}=240\text{sec}$
Hence, distance covered by the particle is given by
$S=v\times t=20\times 240=4800\text{m}=4.8\text{Km}$
