Question

The figure represents the velocity-time graph of body moving in a straight line. How much distance does it travel during the last 10 seconds?

• A. 20 m
• B. 100 m
• C. 50 m
• D. 200 m

Answer 1

The correct option is B 100 m

Distance is $d=velocity\times time$ which is nothing but area under the curve between the limit $t=10s$ to $t=20s$

So, area of triangle is $=\frac{base\times height}{2}=\frac{(20-10)\times 20}{2}=100m$

Hence, correct option is (B).
