Question

light travels from the sun to the planet jupiter in about 2.6x10^3 seconds. The speed of light is approximately 3x10^5 km per second.

what is the approximate distance in km from sun to jupiter?

Answer 1

Distance = speed × time = (3×10^5 km/s) × (2.6×10^3 s) = 7.8×10^8 km.

So approximately 7.8×10^8 km (about 780 million km).
