The Andromeda Constellation is the furthest object we can see with the unaided eye. It is about 22,000,000,000,000,000 km from Earth.

Light travels in space at a speed of about 300,000 km/s. Calculate how many years light takes to reach Earth from the Andromeda Constellation?

Anyone know how I would get the answer?

Thanks
