Based on the distance calculation, how far in miles does a fire truck travel in half an hour at 45 mph?

To determine how far a fire truck travels in half an hour at a speed of 45 miles per hour, you use the relationship between speed, distance, and time. The formula for distance is:

Distance = Speed x Time

In this scenario, the speed is 45 miles per hour. Since the question specifies that the timeframe is half an hour, you need to convert that into hours for consistency in units. Half an hour is equal to 0.5 hours.

Now, substitute the speed and time into the distance formula:

Distance = 45 mph x 0.5 hours

Calculating this gives:

Distance = 22.5 miles

Thus, the correct answer is based on the appropriate use of the formula and correct conversion of time into hours, leading to the conclusion that the fire truck travels 22.5 miles in half an hour at that speed.
