What is traveling faster, an x-ray wave or a radio wave?

The question is so general, so how am I suppose to figure it out without any additional information?

That is question #7 on our worksheet. Question #4 says how many times more energy is there in one photon of an x-ray with a frequency of 1.00E12 hertz or a can of diet pop that has 4184 Joules per can?

Is it somehow related?

They are not related.
Radio waves, x-rays, red light, green light, yellow light, travel at the same speed of 1E8 m/s. It is a general question but you are supposed to know that the speed is the same.
