What is the formula for calculating distance?

1. Distance = Speed / Time

2. Distance = Rate + Time

3. Distance = Rate x Time

4. Distance = Time - Rate

The correct answer is: Distance = Rate x Time

The formula for calculating distance is based on the relationship between distance, rate (or speed), and time. Specifically, distance is determined by multiplying the rate of movement (speed) by the time that movement occurs. This relationship is represented mathematically as Distance = Rate x Time. This formula is derived from rearranging the basic definition of speed, which is the distance traveled divided by the time taken. By manipulating this equation, one can isolate distance, leading to the key formula. This makes it clear that as either the rate of movement increases or the duration of travel extends, the total distance increases accordingly, which is a straightforward yet essential concept in physics and everyday calculations. The other options do not align with the scientifically established formula for distance. For instance, dividing speed by time or adding rate and time does not yield a correct distance measurement. Similarly, subtracting rate from time does not have any meaningful connection to calculating distance. Understanding this fundamental relationship is crucial in various fields, including physics, engineering, and everyday problem-solving.
