Find the no. of seconds in a year and then multiply it to speed of light to get the no. of meters in a light year

Thanks but can you help me with (c) please

ash2326 · Answer

you have light years in meters. Now you convert AU to meters, just multiply by 1000 and then divide the light years by AU ( in meters)
