. Distance = Speed * Time
Let s represent the speed of the cars in miles per hour. The problem statement tells you
.. red car distance + 25 miles = blue car distance
.. s*3 + 25 = s*(3 + 0.5)
.. 25 = 0.5s ... subtract 3s from both sides
.. 50 = s ... multiply by 2
The speed of the red and blue cars is 50 miles per hour.
