Answer:
3.8 x 10¹⁷ in
Explanation:
Light speed= 982,080,000 ft/s
year(time)= 32,000,000 seconds
converting ft/s to in/s for the speed of light:
1ft/s = 12 in/s
982,080,000 ft/s x 12in/s = 11,784,960,000 in/s ( speed of light in inches)
using the standard formula for speed:
V=
Distance( inches)= V (speed in/s) x Time (seconds)
Distance = 11,784,960,000 x 32,000,000
Distance≅ 3.8 x 10¹⁷ in
