WebAverage speed is a scalar, so we do not include direction in the answer. We can check the reasonableness of the answer by estimating: 5 meters divided by 2 seconds is 2.5 m/s. Since 2.5 m/s is close to 2.9 m/s, the answer is reasonable. This is about the speed of a brisk walk, so it also makes sense. WebYes the speed of light is the same in all directions, but what is interesting is that the outcome of the measuring of the speed of light. It remains the same no matter what speed you are moving relative to the light source, or to the …
