Answer:

43 miles per hour

Step-by-step explanation:

We know that in Cherokee County, the speed tickets amounts are calculated on the basis of $17 for each mile above the speed limit.

Since Kirk was fined $221, we can easily calculate the excess speed he was caught at by dividing $221 by $17/mile, which gives us 13 miles.

Since he was caught in a zone where the posted speed limit was 30, and that he exceeded it by 13 miles per hour... we know he was going at 43 miles per hour.
