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=(300)/(85)\text{ m/s}`

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

`\text{distance = speed}*\text{ time}`

substituting;

`\begin{gathered} d=(300)/(85)*395 \\ d=1,394.1\text{ meters} \end{gathered}`

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

`1,394.1\text{ meters}`
