Problem
In one short sentence, explain why two speeds must be expressed in the same unit before their magnitudes are compared.Intuitive explanation
When you compare numbers, you're comparing how many of the same "chunks" each one contains—so if one speed is measured in meters per second and another in kilometers per hour, you're literally counting different-sized chunks, making the comparison meaningless until you convert both to the same unit.
