Answer:

58 miles per hour

Step-by-step explanation:

First you need to divide 80 by 10 to see how many miles she was over the speed limit.

80/10 = 8 miles over the speed limit.

The speed limit was 50, so 50 + 8 = 58 miles.

So Cathy was driving at 58 miles per hour

Answer:

58mph

Step-by-step explanation:

Given:

Each mph over the speed limit gets fined $10

or mathematically, rate of fine = $10/mph

also, total fine was $80.

Number of mph over the speed limit,

= total fine ÷ rate of fine

= $80 ÷ $10/mph

= 8 mph.

Given that the speed limit was 50 mph, Cathy's final speed,

= speed limit + number of mph over speed limit

= 50 + 8

= 58 mph
