If you want to calculate time based on distance and ground speed, what formula would you use?

The correct formula to use when calculating time based on distance and ground speed is derived from the basic relationship between speed, distance, and time. The formula states that time equals distance divided by speed. This means that if you know how far you need to travel (distance) and how fast you are traveling (ground speed), you can easily calculate the time it will take to cover that distance.

In practical terms, if a vehicle travels a certain distance at a specific ground speed, dividing that distance by the speed gives you the total time required to complete the journey. This approach is foundational in physics and is essential in applications like planning travel itineraries, calculating arrival times, and understanding motion in general.

The other options represent incorrect formulations of the relationship between distance, speed, and time or rearrangements that do not yield the time calculation directly.
