Respuesta :

I believe 37.5 because you would divide 225 by 6 making it 37.5. If you divide all of them by the number above they will all be 37.5

Answer:

37.5 miles per hour

Step-by-step explanation:

To find the miles per hour, you divide the miles by hours. If you divide 225/6, you get 37.5. You can double check this by dividing another set, like 450/12 and see that you still get 37.5. Hope this helps! :)
