The minimum fine for driving in excess of the speed limit is $25. An additional $6 is added to the minimum fine for each mile per hour (mph) in excess of the speed limit. Rachel was issued a $103 fine for speeding in a 55-mph speed limit zone. At what speed, in mph, was Rachel driving when she was fined?

Given the speeding fine guidelines, and Rachel's total fine of $103, it can be calculated that she was driving at 68 miles per hour when she received the fine. ;

Let the excess speed limit be y.
According to your question,
25 + 6y = 103
6y = 103 - 25 = 78
y = 78/6 = 13
Thus, the excess speed was 13 mph.
Thus, speed of Rachel = 55 + 13 = 68mph
Thus, Rachel was driving at 68 mph.
