Answer 2

Given,

The distance covered in km$\[ = \frac{{18}}{5}\]$

The time duration to cover the distance in hours$\[ = 1\]$

Solution,

Formula used,$\[{\rm{Distance}} = {\rm{Speed}} \times {\rm{Time}}\]$

So, the speed of Surya is

$\[\begin{array}{l} \Rightarrow \frac{{\frac{{18}}{5}}}{1}\\ \Rightarrow \frac{{18}}{5}{\rm{km}}/{\rm{hr}}\end{array}\]$

Therefore, the distance covered in $\[\frac{5}{2}\]$hours is

$\[\begin{array}{l} = \frac{{18}}{5} \times \frac{5}{2}\\ = \frac{{18}}{2}\\ = 9{\rm{km}}\end{array}\]$

Hence, the distance covered is $\[9{\rm{km}}{\rm{.}}\]$
