How far does a beam of light travel in one full year? A) 80 × 10¹² m B) 95 × 10¹⁴ m C) 30 × 10⁸ m D) 20 × 10¹⁵ m E) 36 × 10¹⁶ m

Question

Quizplus · Accepted Answer

A beam of light travels at a speed of approximately 3×10^8 meters per second. In one year, there are 365 days, each with 24 hours, each with 60 minutes, each with 60 seconds. Therefore, the distance a beam of light travels in one year is:
3×10^8 m/s × 60 s/min × 60 min/hr × 24 hr/day × 365 days/year
Simplifying:
= 3×10^8 × 60 × 60 × 24 × 365 meters
= 9.46×10^15 meters
The closest option to this value is B: 95 × 10^15 meters, which is the best choice.
