Light travels at an approximate rate of 1.9 x 10^5 mi./sec. There are about 3.2 x 10^7 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.
____ miles
To find the number of miles light travels in a year, we need to multiply the speed of light (1.9 x 10^5 mi/sec) by the number of seconds in a year (3.2 x 10^7 sec).
1.9 x 10^5 mi/sec * 3.2 x 10^7 sec = 6.08 x 10^12 mi
Therefore, light travels approximately 6.08 x 10^12 miles in a year.
To calculate how many miles 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 x 10^5 mi./sec
Number of seconds in a year = 3.2 x 10^7 sec
Multiplying these two numbers will give us the total distance traveled:
(1.9 x 10^5 mi./sec) * (3.2 x 10^7 sec)
To multiply the numbers in scientific notation, we multiply the coefficients (1.9 * 3.2) and add the exponents (5 + 7):
(1.9 * 3.2) x 10^(5 + 7) = 6.08 x 10^12 miles
So, light travels approximately 6.08 x 10^12 miles in a year.
To calculate the number of miles light travels in a year, we need to multiply the speed of light by the number of seconds in a year.
Speed of light = 1.9 x 10^5 mi./sec
Number of seconds in a year = 3.2 x 10^7 seconds
To calculate the number of miles light travels in a year, we multiply the speed of light by the number of seconds in a year:
Miles traveled = (1.9 x 10^5 mi./sec) * (3.2 x 10^7 seconds)
To multiply numbers in scientific notation, we multiply the coefficients and add the exponents:
Miles traveled = (1.9 * 3.2) x (10^5 * 10^7) mi.
Multiplying the coefficients gives us 6.08.
When multiplying numbers with the same base, we add the exponents:
10^5 * 10^7 = 10^(5+7) = 10^12
So, Miles traveled = 6.08 x 10^12 mi.
Therefore, light travels approximately 6.08 x 10^12 miles in a year.
