I am unfortunately not too sure about this, I have not heard of a proportional equation before even after getting my degree, because an equation usually isn't proportional, only expressions are and there are usually 2 terms.
Here's my best attempt. The first equation isn't proportional since y is inversely proportional to the 7 in the denominator. The second is proportional, and the k constant is 10.
I cannot provide any further explanations.
Let me know if this was helpful!

You are given
the distance of the horse of 45 miles at 15miles per hour and another 35 miles
at 10 miles per hour. You are asked the total time in hours of the cowboy
riding his horse. You have to get the time each mile the cowboy rode.
45 miles/15
miles per hour = 3 hours
35 miles/10
miles per hour = 3.5 hours
<span>3 hours + 3.5
hours = <u>6.5 hours</u>
</span>
<span>So the answer
is B. 6.5 hours.</span>
