Answer: the answer to this is  9 miles an hour

Step-by-step explanation: 1. What this is asking is to make the fraction a bit easier to understand. So all we do is divide the numerator by the denominator. You can use this method for any other math problems like this also.  

2.  All this chart is doing is multiply the input or output by 9. If you look you can see the hours is multiplied by nine. I hope this helped.
