To calculate:

Number of seconds counted for a thunderstorm that is $2miles$ away .

Answer to Problem 17Q

Number of seconds counted for a thunderstorm that is $2miles$ away is $10\sec onds$

Explanation of Solution

Given information:

Distance from which a person is away from thunderstorm $2miles$

Calculation:

Here, variable is given representing the number of seconds between time when a person see lighting and time when a person hear thunder.

Given define variable is $x$ as seconds counted, So equation for that after dividing by $5$,

  $2=\frac{x}{5}$

Now multiply both sides by $5$

Equation will be,

  $\begin{array}{l}2.5=x\\ 10=x\end{array}$

Therefore, Number of seconds counted for a thunderstorm that is $2miles$ away is $x=10\sec onds$
