In an effort to reduce accidents, the highway authority decided to reduce the speed limit on a road from 65 mi/h to 50 mi/h. To travel 650 miles, how many more hours will it take a car averaging 50 mi/h than a car averaging 65 mi/h?

The answer is 3 hours

Step-by-step explanation:

The reason being, 65 mi/h can be divided by 650 to equal 10, so it would take 10 hours to get through those 650 miles with your car that drives 65 mi/h

Then we can do the same things with 50, that equals 13. So 13 - 10 = 3. It took the 50 mi/h car 3 more hours to get through 650 miles than the 65 mi/h car!

Hope this helped :)

step-by-step explanation:

first option

a function is a relation in which an input is paired with exactly one output.

so, let's find the right answer.

in our first option, our inputs are january, february, and march. the outputs are 30, 28, and 25. each input has it's own output. this is correct!

our second option we know is incorrect, because ms. valverade has two outputs, dogs and cats. this is not a function.

our third option is incorrect as well. the yellow square has two ouputs, the square and the triangle.

lastly, in our fourth option, we see the number 7 two times with a different output. therefore, this is not a function.

remember: each input must be paired with only one output!
