Answer:

Step-by-step explanation:

30.2 miles / 2/3 hour

This is saying 30.2 divided by 2/3. When you divide by a fraction you have to multiply by the inverse

30.2 x 3/2

90.6 / 2

45.3 miles per hour

Actually, the domain is the possible set of input values of a function that will make the function fit the specific criteria. In this case, the input value is m, where m is the number of miles that is travelled. The criteria is to travel at least 10 miles but not more than 30 miles, therefore the domain should be:

 

All real numbers from 10 to 30, inclusive

 

(should be real numbers not integer since any fractional number is included in the domain)

 

I cannot figure out why the choices are far from the answer.
