Here's why:
* Velocity is speed with direction: A car traveling at 60 mph east is moving at the same speed as a car traveling 60 mph west, but their velocities are different because they're going in opposite directions.
* Time is needed to calculate travel time: To determine how long it takes to travel a distance, you need both the velocity and the distance. The formula is:
Time = Distance / Velocity
Example:
Let's say you're driving at a constant velocity of 60 mph and you need to travel 120 miles.
* Time = 120 miles / 60 mph = 2 hours
Therefore, velocity alone doesn't tell you the time taken. You need the distance as well.
