Light in vacuum travels at a speed of 3.00 x 10^8 m ^-1 s^-1 on average earth is 93,000,000 miles from the sun how many minutes does it take sunlight to reach the earth show work please

The correct unit for the speed of light is  [ m s⁻¹ ].Time = (distance) / (speed)Time = (9.3 x 10^7 miles) x (1609 m/mile) / (3 x 10^8 m/s) = 498.8 seconds .That would be  8.31 minutes.
