correct answer is: a) 202\large\frac{1}{2}

Explanation

Here,
Speed = 45 km/hr
Time =4\large\frac{1}{2} or \large\frac{9}{2} hours
We know,
Distance = Speed \times Time
\therefore The distance between Calcutta to Digha is:
\rightarrow\left(45\times\large\frac{9}{2}\right) km
\rightarrow\large\frac{405}{2} km
\rightarrow 202\large\frac{1}{2} km
Ans: The distance between Calcutta to Digha is 202\large\frac{1}{2} or 202.5 km.
