hi all, having problem with 1 question.
speed of light = 2.998 x 10^8m/s
AU(average distance from Earth to sun) = 1.50 x 10^8km
what i tried doing was converting speed of light into km/h then dividing the two and vice versa. i keep getting 7183.#### something along those lines.
but the answer is simply 7.20 AU's(using significant figures) am i getting the right answer and don't know how to write it? or am i not working it out correctly?
thanks
