A)
light travels at approximately 186,000 miles per second. approximately how far will it travel in 1 minute? express your answer in scientific notation
B)
the sun is approximately 93,000,000 miles from the earth. about how long does it take light to travel from the sun to the earth? remember that light travels at approximately 186,000 miles per second
(A) 186,000*60 = 1.116*10^7 miles
(B) 93,000,000/186,000 = 5*10^2 seconds

A) To find out how far light will travel in 1 minute, we need to multiply the speed of light by the number of seconds in a minute.
Speed of light = 186,000 miles per second
Number of seconds in 1 minute = 60 seconds
To find the distance light will travel in 1 minute, we multiply:
186,000 miles/second * 60 seconds = 11,160,000 miles
To express this answer in scientific notation, we can write it as:
11.16 x 10^6 miles
B) To determine how long it takes for light to travel from the sun to the earth, we can divide the distance between the sun and the earth by the speed of light.
Distance from the sun to the earth = 93,000,000 miles
Speed of light = 186,000 miles per second
To find the time it takes for light to travel, we divide:
93,000,000 miles / 186,000 miles/second = 500 seconds
To convert this time into minutes, we divide by 60:
500 seconds / 60 = 8.33 minutes
So, it takes approximately 8.33 minutes for light to travel from the sun to the earth.
