Explanation / Answer

Ans 8

Distance between earth and sun = 92.96 million miles

Distance in meters = 92.96 million miles x 1.609km/mi

= 149.57264 million km x 1000m/km

= 149572.64 million meters x 10^6 / million

= 149572640000 meters

Time to take for the first beam of light

= distance / speed of light

= (149572640000 meters) / (2.9*10^8 m/s)

= 515.76 s x 1min/60s

= 8.59 s
