A student calculates the time taken (in minutes) for the light from the sun to reach the Earth. The sun is 93 million miles away (1 mile 1.609 km) and the speed of light is 3.00 x 108 m/s. The calculation is set up as follows: 9.3 x 10^7 mi x 1609 km/1 mi x 10^3m/1 km x 1 s/3.00 x 10^8 m x 1 min/60s Select the correct answer, quoted to the correct number of significant figures. O 8.3 min, since 9.3 x 10 has 2 significant figures O 8.313, since 1.609 has 4 significant figures O 8 min, since there is only 1 significant figure in 60 s O 8.31 min, since 3.00 x 10° has 3 significant figurts
