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

Divide the distance by the speed, then convert seconds into years (divide by 60 to get to minutes, another 60 to get to hours, another 24 to get to days and 365 to get to years).

I hope this helps. Thanks for asking.
