Given that the average speed is distance 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 written scientific notation

m = 5 and n = 2

Explanation:

We know that the distance of the sun from the Earth is about 150 million km and the speed of light is .

Average speed = distance/time

or

time = distance/speed

So,

In scientific notation :

The general form of scientific notation is

On comparing, we find that m = 5 and n = 2
