Question The use of electricity in the US in 1902 was 6.03 x 10^9 kilowatt-hours. The use of electricity in the US in 1950 was 4.3 x 10^11 kilowatt-hours. What was the total kilowatt-hours of electricity used during these two years?

Answer 1

To find the total kilowatt-hours of electricity used during these two years, you simply need to add the electricity used in 1902 to 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

Total electricity used = 6.03 x 10^9 + 4.3 x 10^11
Total electricity used = 6.03 x 10^9 + 430 x 10^9
Total electricity used = 436.03 x 10^9 kilowatt-hours
Total electricity used = 4.36 x 10^11 kilowatt-hours

Therefore, the total kilowatt-hours of electricity used during these two years was 4.36 x 10^11 kilowatt-hours.
