Radio waves travel at the speed of light, 299 792 458 m / s.
To get the distance travelled within a span of time, we simply use the formula: d = vt, where v is the speed and t is the time.
`d = 22.27 min (60 sec/min) (299792458 m/sec) = 4.01 x 10^(11).`
`d = 3.03 min (60 sec/min)(299792458 m/sec) = 5.45 x 10^(10) `
The distance between aphelion and perihelion is the sum of these two quantities:
4.01E+11 + 5.45E+10 = 4.56 x 10^11 meters.
