Alright, so for this problem...
We first need to identify what a unit rate is. The unit rate describes the relationship between an amount and what unit it can be associated with. For example, 2 feet per second, where the amount is two and the unit is seconds. In the sense of this problem, we can make up something, such as 14 feet for every 8 seconds.
If I understand your question correctly, you need to find how many feet you'll gain in 1 second. This is accomplished by solving for the ratio of feet to second:
[tex]14/8=1.75[/tex]
This means that there's a 1:1.75 ratio of seconds to feet. You can check this by multiplying the number of seconds by 1.75 to get the number of feet:
[tex]8*1.75=14[/tex]
Now all that's left is to plug our value of 1 second where we placed 8 seconds, and we will have our answer.
[tex]1*1.75=1.75[/tex]
For every one second, 1.75 feet is travelled.
You could also accomplish this/check your work further by graphing this problem. I've attached a graph for you to reference.
Hope this helped you out! Feel free to ask me any additional questions if you have any. :-)
