Light travels about 180 million kilometers in 10 minutes. How far does it travel in 1 minute ? How far does it travel in 1 secon
daser333 [38]

Answer:18 million and 300000

Step-by-step explanation:

Since light travels 180 million KM in 10 min, it would travel 180 million/10 in one minute. Thus, we get 18 million. As we know, there are 60 seconds in a min. Thus, there are 60*10=600 seconds in 10 minutes. Thus, 180 million/600 gives 300000

How do I factor an expression using the GCF?
Anni [7]

Answer:

  use the distributive property

Step-by-step explanation:

Use the distributive property to rewrite the expression with the GCF factored out.

<u>Example</u>:

  ab +ac +ad  . . . . has terms with a common factor of 'a'

When the common factor is factored out, the distributive property tells you the equivalent is ...

  = a(b +c +d)

If 'a' is the greatest common factor, then b, c, d are mutually prime and no more factors can be removed to outside the parentheses.
