Two cars are moving parallel to each other on a road. The first car is moving at a speed of 11 m/s, while the second car is moving at 17 m/s, what is the speed of the second car, relative to the first car.
The relative speed of the second car, with respect to the first car is 6 m/s. This is because they are both travelling in the same direction, but the second car is moving 6 m/s faster. That means, if we were to be sitting in the first car, we would observe the second car moving ahead of us at a speed of 6 m/s.
