Answer:
Explanation:
[tex]\text{Average Speed=}\frac{\text{Distance}}{Time}[/tex]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:
[tex]Average\; Speed=\frac{5}{30}=\frac{x}{45}[/tex]We solve for x.
[tex]\begin{gathered} x\times30=5\times45 \\ x=\frac{5\times45}{30} \\ x=7.5\operatorname{km} \end{gathered}[/tex]
