Answer:1. SPEED:Formula:Distance is the total path traveled.Time is the duration of travel.Example: If a car travels 100 kilometers in 2 hours, the speed would be:2. ACCELERATION:Formula:Change in Velocity is the final velocity minus the initial velocity.Time Taken is the duration over which the velocity change occurs.Example: If a car accelerates from 0 to 20 m/s in 5 seconds, the acceleration is:3. Velocity:Formula:Displacement is the shortest straight-line distance from the starting point to the endpoint.Time is the duration of the travel.Example: If a person walks 30 meters north in 6 seconds, the velocity would be:Summary of Differences:SPEED is a scalar quantity (no direction).VELOCITY is a vector quantity (has both magnitude and direction).ACCELERATION is the rate at which velocity changes over time
