#3.0 × 10^8\ "m/s"#

Explanation:

Radio wave is an electromagnetic wave. Speed of electro magnetic wave in vacuum is approximately #3 × 10^8\ "m/s"#

It can be proved by the values given. Relation between speed #("v"),# Frequency #("f")# & wavelength #("λ")# is

#"v = f λ"#

#"v" = 543 × 10^6\ "Hz" × "0.55 m"#

#"v" = 2.9865 × 10^8\ "m/s" ≈ 3.0 × 10^8\ "m/s"#
