Chris went on a bike ride of 24 miles. He realized that if he had gone 8 mph faster, he would have arrived 4 hours sooner. How fast did he actually ride?

Total miles = rate x time

We can set up 2 eq:

24 = (x+8) (y-4)

24=xy

Where x is equal to my original rate

and y is equal to the original time spent traveling the 2mi

We can now solve for one of the variables and find our rate
