The speed of light is 1.86×10^5 miles per second. how many miles will light travel in 4,200,000 seconds?

Step-by-step explanation:

Let be "x" the amount of miles light will travel in 4,200,000 seconds.

Rewrite 4,200,000 seconds in Scientific notation. Move the decimal point 6 places to the left. Then:

According to the exercise, light travels miles in 1 second.

Therefore, based on this data, you can set up the following proportion:

And finally, you must solve for "x" in order to find its value.

(Remember the Product of powers property: )

Then:

x equals 1

step-by-step explanation:

f(4)=f(×)

x=1
