ok so far i have
light from the sunr eaches Earth in 8.3 min.
The velocity of light is 3.00 x 10 to the eighth power m/s . How far is Earth from the sun
so far i have the formula Delta d ( avg distance) = v (velocity) x delta t(avg speed)
so far i converted 8.3 minutes = 8.3 x 60 = 498= 500 < -- do i use sig figs?
and my final equation became delta d = (3.00x10 to the eight power) x 500 = 1.5 x 10 to the eleventh power.. somehow i don't think its right.. because i looked at the answer key and it said 2.5 m/s please help me get the right steps
