Light travels at an approximate rate of 1.9×105 mi./sec. There are about 3.2×107 seconds in a year. About how many miles does light travel in a year? Write the answer in scientific notation. Express the answer to the exact decimal place.

Answer 1

To find out how many miles light travels in a year, we can multiply the speed of light (1.9×105 mi./sec) by the number of seconds in a year (3.2×107 seconds).

1.9×105 mi./sec × 3.2×107 seconds

Multiplying these two numbers together gives us the distance in miles that light travels in a year:

6.08×1012 miles

Therefore, light travels approximately 6.08×1012 miles in a year.

Answer 2
