Given that average speed is distance traveled divided by time, determine the values of m and n when the time it takes a beam of light to get from the Sun to the Earth (in s) is written in scientific notation. Note: the speed of light is approximately 3.0×108 m/s.

Respuesta :

If speed = distance/time , then time = speed/distance.

So...

Speed of light = 3*10^8(m/s)
Average distance from Earth to Sun = 149.6*10^9(m)

Therefore, t=(3*10^8(m/s))/(149.6*10^9(m))

I hope this was a helpful explanation, please reply if you have further questions about the problem.

Good luck!

The time it takes a beam of light to get from the Sun to the Earth is [tex]4.99\times 10^2secs[/tex]

The formula for calculating the average speed is expressed according to the formula:

[tex]Speed= \frac{distance}{time}[/tex]

Given the speed of light as [tex]3.0 \times 10^8m/s[/tex]

Distance from earth to the sum is [tex]149.6\times 10^9m[/tex]

Substitute the given parameters into the formula to get the time "t"

[tex]t=\frac{d}{t} \\t=\frac{149.6\times10^9m}{3.0\times10^8}\\t=49.87\times 10\\t =498.7secs[/tex]

Hence the time it takes a beam of light to get from the Sun to the Earth is [tex]4.99\times 10^2secs[/tex]
