(a) 16.777mi

(b)Yes, he was speeding

Explanation:

(a)

Let's do the proper operations in order to convert km to mi:

We can conclude that the trip length in miles was:

(b)

Let's calculate the speed of the man during the trip:

But first, let's do the proper operations in order to convert min to h:

Now, the speed is:

As we can see:

So, we can conclude that the driver was speeding

the old price per ounce is c/4.

the new price per ounce is c/3.6.
