To find the total kilowatt-hours of electricity used during these two years, we need to add the electricity used in 1902 and the electricity used in 1950.
Electricity used in 1902 = 6.03 x 10^9 kilowatt-hours
Electricity used in 1950 = 4.3 x 10^11 kilowatt-hours
Adding these two values together: (6.03 x 10^9) + (4.3 x 10^11) = 4.3 x 10^11 + 6.03 x 10^9 = 4.3 x 10^11 + 0.603 x 10^11 = 4.903 x 10^11 kilowatt-hours
Therefore, the total kilowatt-hours of electricity used during these two years was 4.903 x 10^11 kilowatt-hours.
