50000000 km is a looooooong way.
You may think it's a long way to the shops but that is nothing compared to Space...
150000000 km is the approximate mean distance from the earth to the sun - the earth follows an elliptical orbit.
Distance to the sun.
Planet Earth.

150000000 x 50000 = 7500000000000
150000000 x 1000000 = 150,000,000,000,000
The speed of light (light is an electromagnetic wave) is 299,792,458 metres per second - which is 1,079,252,849km/hour. So; 150000000 / 1079252849 = 0.13899 hours = 8 minutes and 20 seconds.
An astronomical unit (AU) is a unit of measurement used in astronomy to describe distances within the solar system. One AU is roughly equal to the average distance from the Earth to the Sun, which is about 150,000,000 km.

To convert kilometers to meters, you multiply by 1,000 (since 1 kilometer equals 1,000 meters). Therefore, 150,000,000 kilometers is equal to 150,000,000,000 meters, or 150 billion meters.
