Question

Eleanor can run 300 meters in 85 seconds. If their speed remains constant, how many meters could they run in 395 seconds? Round to one decimal.

Answer 1

Given that Eleanor can run 300 meters in 85 seconds;

$r=\frac{300}{85}\text{ m/s}$

We want to calculate how many meters it can run in 395 seconds;

$\text{distance = speed}\times\text{ time}$

substituting;

$\begin{gathered} d=\frac{300}{85}\times395 \\ d=1,394.1\text{ meters} \end{gathered}$

Therefore, the distance they can run in 395 seconds is;

$1,394.1\text{ meters}$
