Final answer:
The speed of a taxi can be determined by calculating the gradient of the line representing its distance covered at each second. Ignoring speed limits can lead to accidents and penalties, such as traffic tickets. Being aware of the ideal speed is crucial when driving a taxi.
Step-by-step explanation:
The speed of a taxi can be determined by calculating the gradient of the line representing its distance covered at each second. If the distance covered by the taxi increases at a steady rate, it indicates that the taxi is accelerating and its speed is increasing over time. On the other hand, if the distance covered remains constant, it indicates that the taxi is traveling at a constant speed.
It's important to follow the speed limits while driving a taxi to ensure safety and avoid traffic violations. Ignoring speed limits can lead to accidents and penalties, such as traffic tickets. Being aware of the maximum safe speed at which a vehicle can turn on a curve without relying on friction with the road is crucial when driving a taxi. This speed, known as the ideal speed, is determined by the characteristics of the curve and the vehicle's tires.
