(A) Which Car Was Travelling At A Sted Speed?
To determine which car was traveling at a steady speed, you will need additional information. A steady speed implies that the car's velocity remains constant over a period of time.
If you have access to the cars' speed and time measurements, you can compare the velocities of each car at different points in time. Look for a car that maintains the same speed throughout the recorded time intervals.
You can calculate the velocity of each car using the formula:
Velocity = Distance / Time
Once you have the velocities determined for each car at different points in time, identify the car with the least variation in velocity. If one car maintains a consistent velocity while the others exhibit fluctuations in speed, the car with the consistent velocity is the one traveling at a steady speed.
