Question

WEATHER 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.

Time (t) 5 10 15
Distance (d) 1 2 3
The equation
t
=
5
d
shows the relationship between the time, t, in seconds and the distance, d, in miles. Solve the equation for d.

Answer 1

To find the distance to a lightning strike, use the equation t = 5d. For a 5-second interval, the distance is 1 mile.

Step-by-step explanation:

To solve the equation for the distance to a lightning strike, you need to use the equation t = 5d, where t is the time in seconds between seeing the lightning and hearing the thunder, and d is the distance in miles. If you count 5 seconds after seeing the lightning before you hear the thunder, you simply substitute 5 for t in the equation and solve for d.

Using the given equation:

1. Substitute the value of t with 5 seconds: 5 = 5d.
2. Divide both sides of the equation by 5 to solve for d: d = 5 / 5.
3. Simplify the right side of the equation to find the value of d: d = 1.

Therefore, the distance to the location of the storm is 1 mile.
