Final answer:
The car advertisement is describing the acceleration of the car. You could drive the car at exactly 50 mph and then apply the accelerator until it reaches the speed of 60 mph and record the time it takes. Acceleration is a concept in physics that refers to the rate of change of velocity over time.
Step-by-step explanation:
The car advertisement is describing the acceleration of the car, specifically the time it takes for the car to go from a stopped position to a speed of 60 miles per hour.
To measure this time, you could drive the car at exactly 50 mph and then apply the accelerator until it reaches the speed of 60 mph and record the time it takes.
Acceleration is a concept in physics that refers to the rate of change of velocity over time. In this case, the car's acceleration would be measured in seconds.
