Why is miles per hour a rate even though neither miles nor hours are rates themselves.

this is a really stupid question

Miles and hours are each units of measure, while mph is the ratio between them. Miles and hours are units of measure, and mph is the product of the two. Rates can never be used to measure things.

The correct option is B) Jorge incorrectly combined like terms.

Step-by-step explanation:

Consider the provided equation:

Step 1: Remove the parentheses and apply the distributive property: a(b+c)=ab+ac.

Step 2: Now add the like terms.

Step 3: Isolate the variable:

Step 4: Now divide the both side by 3.

Now compare the above steps with the steps perform by Jorge.

By observing we can identify that the Jorge incorrectly combined like terms.

Hence, the correct option is B) Jorge incorrectly combined like terms.
