how many years could it power?

Question

50 million barrels of oil (or 50 million barrel of oil equivalents) imagine that all of that energy was instead used to light one 60-watt light bulb.assuming the light bulb never burned out, how many yrs. Could it be powered? Note:1 boe= to 1,700,00 watt-hrs. A watt-hrs is a watt expended for 1 hr. (Not one watt per hr) Plz show work

Answer 1

Should 1,700,00 read 1,700,000? Let's assume it does=1.7E6 in scientific notation.
1boe=1.7E6 watt-hrs, so 5E7 boes=8.5E13 watt-hours. A 1-watt bulb would last 8.5E13 hours, so a 60w bulb would be 60 times less=8.5E13/60=1.417E12.
There are 8.766E3 hours in a year of 365.25 days, so the bulb would burn for 1.417E12/8.766E3=1.616*10^8 years!
If 1boe=170,000 watt-hrs then the light bulb could be powered for 1.616*10^7 years, or 16,160,000 years.

Yes, it should have read 1,700,000 thx for your help!
