Question

KCSamin can run 5 kilometers in 30 minutes. Assuming she keeps a constantpace, how many kilometers can she run in 45 minutes?kilometers

Answer 1

Answer:

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:

$Average\; Speed=\frac{5}{30}=\frac{x}{45}$

We solve for x.

$\begin{gathered} x\times30=5\times45 \\ x=\frac{5\times45}{30} \\ x=7.5\operatorname{km} \end{gathered}$
