Question

you can approximate the distance to a lightning strike by counting the seconds between the flash of lightning and the sound of thunder. this table shows the relationship between time and distance.
the equation t = 5d shows the relationship between the time, t, in seconds and the distance, d, in miles. solve the equation for d.

time (t)	distance (d)
10	2
15	3

Explanation:

Step1: Isolate the variable d

Given the equation $t = 5d$, we want to solve for $d$. Divide both sides of the equation by 5.
$\frac{t}{5}=\frac{5d}{5}$

Step2: Simplify the right - hand side

Since $\frac{5d}{5}=d$, the simplified equation is $d=\frac{t}{5}$.

Answer:

$d = \frac{t}{5}$
