To calculate distance, which formula should be used?

The formula for calculating distance relies on the relationship between speed, time, and distance itself. The correct formula is derived from the basic definition of speed, which is the distance traveled per unit of time. Specifically, to find the distance, one needs to multiply speed by the time taken for the journey.

When you think about it intuitively, if a vessel is traveling at a certain speed and you want to determine how far it has traveled in a specific amount of time, you take the speed (how fast it's going) and multiply that by the time (how long it's been traveling). This gives you the total distance covered. For example, if a boat moves at a speed of 10 knots for 2 hours, the distance it travels is 10 knots multiplied by 2 hours, equating to 20 nautical miles.

The other options do not correctly describe how to calculate distance in this context. For instance, dividing speed by time would give you a rate or an acceleration, not distance. Similarly, distance divided by speed would yield time, and time divided by speed would yield a reciprocal value that doesn't directly translate to a distance measurement. Therefore, the formulation of distance being calculated as speed multiplied by time is the foundational concept that makes understanding
