Answer:

Step-by-step explanation:


\text{Average Speed=}\frac{\text{Distance}}{Time}

Samin can run 5 kilometres in 30 minutes.

Since she keeps a constant pace, the average speed will be the same.

Let the distance she covered in 5 minutes = x

Therefore:


Average\; Speed=(5)/(30)=(x)/(45)

We solve for x.


\begin{gathered} x*30=5*45 \\ x=(5*45)/(30) \\ x=7.5\operatorname{km} \end{gathered}
