We'll take your word for it and use the distance of 400 million km.
The speed of radio (and light, heat, UV, X-ray, etc.) is 300,000 km/sec.
Time = (400 x 106) / (300 x 103) = 1,333 seconds = 22.2 minutes

The Apollo spacecraft traveled at a maximum speed of 24,000 mph. To overcome the Earth's gravitational pull, one must travel at or above its escape velocity which is 24,000 mph.
