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
please help me.
(B i don't understand)
answered above
time equals 1 sec
distance =186,000 mi and 300,000km
what is the scientific notation
A) To calculate how far light will travel in 1 minute, we need to multiply the speed of light by the number of seconds in a minute.
The speed of light is given as approximately 186,000 miles per second. Since there are 60 seconds in a minute, we can calculate the distance traveled in a minute by multiplying the speed of light by 60:
186,000 miles/second * 60 seconds = 11,160,000 miles
Expressing this answer in scientific notation, we can write it as:
1.116 x 10^7 miles
B) To determine how long it takes light to travel from the sun to the earth, we can divide the distance between them by the speed of light.
The distance from the sun to the earth is approximately 93,000,000 miles, and the speed of light is approximately 186,000 miles per second.
To calculate the time it takes, we divide the distance by the speed:
93,000,000 miles / 186,000 miles/second = 500 seconds
Expressed in scientific notation, this is:
5.00 x 10^2 seconds
To convert this into minutes, divide the seconds by 60:
500 seconds / 60 seconds/minute = 8.33 minutes
Therefore, it takes light approximately 8.33 minutes to travel from the sun to the earth.
