    A tiger chases a deer 30 m ahead of it and gains 3 m in 5 s after the chase began. The distance gained by the tiger in 10 s is

    A)  6 m                                       

    B)  12 m

    C)  18 m                                    

    D)  20 m

    E)  16 m

    Correct Answer: B

    Solution :

                    If \[a\] is the relative acceleration, then \[3=\frac{1}{2}a\times 5\times 5\] \[a=\frac{6}{25}m\text{/}{{s}^{2}}\] Again,  \[s=\frac{1}{2}\times \frac{6}{25}\times 10\times 10\]                 \[=11\,m\]
