    A tortoise and a hare compete in a race over a course 2.00 km long. The tortoise crawls straight and steadily at its maximum speed of 0.200 \[m{{s}^{-1}}\]towards the finish line. The hare runs at its maximum speed of 1.6 \[m{{s}^{-1}}\]towards the goal for 1.6 km and then stops to tease the tortoise. The time taken by tortoise to reach the finish line is.

    A) \[4\times {{10}^{4}}\sec \]  

    B)          \[{{10}^{4}}\sec \]

    C) \[{{10}^{3}}\sec \]  

    D)          \[4\times {{10}^{3}}\sec \]

    Correct Answer: B

    Solution :

        \[\text{Time=}\frac{\text{Distance}}{\text{Speed}}=\frac{2\times {{10}^{3}}m}{0.2\,m{{s}^{-1}}}={{10}^{4}}\sec \]
