f the fire continues to spread at a pace of 7 miles per hour, how long will it take the fire to reach the burn perimeter trench created by the firefighters? Show all work to support your answer.
To find the time it will take for the fire to reach the burn perimeter trench, we need to determine the distance between the fire and the trench. Let's denote this distance as "d".
Since the fire is spreading at a rate of 7 miles per hour, the distance it covers in 1 hour is 7 miles. In terms of a formula:
Distance = Rate × Time
We can rearrange this formula to solve for time:
Time = Distance ÷ Rate
Using the given information, we know the rate is 7 miles per hour. Let's assume the distance between the fire and the trench is 42 miles (just as an example). Plugging these values into the formula:
Time = 42 miles ÷ 7 miles/hour
Time = 6 hours
So if the distance between the fire and the trench is 42 miles, it will take the fire 6 hours to reach the trench.
