What is the impact speed when a car moving at 300 km bumps into the rear of another car traveling in the same direction at 88 km Answer in units of km?

The impact speed when the car traveling at 300 km/h bumps into the rear of the other car traveling at 88 km/h is 212 km/h. This is calculated by subtracting the speeds (300 km/h - 88 km/h = 212 km/h).
