Correct Answer: উত্তরঃ কুকুর ও খরগোশের গতিবেগ ১৬ ৪ ১৫ ।

Explanation:

ধার, খরগোশ 4 লাফে যায় =xমিটার

খরগোশ 1 লাফে যায় =$\frac{x}{৪}$ মিটার

খরগোশ 5 লাফে যায় =$\frac{৫x}{৪}$ মিটার

আবার, কুকুর 3 লাফে যায় = x মিটার

কুকুর 1 লাফে যায় =$\frac{x}{৩}$ মিটার

কুকুর 4 লাফে যায় =$\frac{৪x}{৩}$ মিটার

বেগের অনুপাত =$\frac{৪x}{3}$ঃ$\frac{৫x}{৪}$=১৬ঃ১৫
