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.(1 point)
To find the distance light travels in a year, we can multiply the speed of light by the number of seconds in a year.
Speed of light = 1.9 × 10^5 mi/sec
Number of seconds in a year = 3.2 × 10^7 seconds
Distance traveled in a year = Speed of light × Number of seconds in a year
= (1.9 × 10^5 mi/sec) × (3.2 × 10^7 seconds)
Now we can multiply the two numbers together:
(1.9 × 10^5) × (3.2 × 10^7) = 6.08 × 10^12
Therefore, light travels approximately 6.08 × 10^12 miles in a year.
