The speed of light is about 300,000 kilometers per second. convert the speed to miles per hour. round your answer to the nearest hundred thousand miles per hour

671080887.619  miles/hour        

Step-by-step explanation:

Given : Speed of light = 300,000 kilometers per second

To Find:  Convert the speed to miles per hour

Solution :

1 kilometer = 0.621371 miles

3600 second = 1 hour

So, 1 second =

So, speed of light in miles per hour:

=

=

=

Thus the speed of light is 671080887.619  miles/hour

step-by-step explanation:

step 1: simplify both sides of the equation.

7x+8(x+

)=3(6x−9)−8

7x+(8)(x)+(8)(

)=(3)(6x)+(3)(−9)+−8(distribute)

7x+8x+2=18x+−27+−8

(7x+8x)+(2)=(18x)+(−27+−8)(combine like terms)

15x+2=18x+−35

15x+2=18x−35

tep 2: subtract 18x from both sides.

15x+2−18x=18x−35−18x

−3x+2=−35

step 3: subtract 2 from both sides.

−3x+2−2=−35−2

−3x=−37

step 4: divide both sides by -3.
