Question

The time between a flash of lightning and the sound of its thunder can be used to estimate the distance from alightning strike. The distance from the strike is the number of seconds between seeing the flash and hearing thethunder divided by 5. Suppose you are 2 miles from a lightning strike. Write and solve an equation to find howmany seconds there would be between the flash and thunder.

Answer 1

Given:

Distance from the strike = 2 miles

The objective is to find the time between a flash of lightning and the sound of its thunder.

According to the question,

`\text{distance}=(time)/(5)`

Substitutig the values,

`\begin{gathered} 2=\frac{\text{time}}{5} \\ \text{time=2}*5 \\ =10\text{ seconds} \end{gathered}`

Hence, the time between the flash and thunder is 10 seconds.
