I'm having trouble just figuring out how to set these problems up. Here is one of them. A jogger and a walker both cover a distance of 5 miles. The runner is traveling 1.5 times faster than the walker and finishes in 25 minutes less time. How fast is each going? I know it probably should include the r*t=d So I "tried" to make a table jogger = rate = 1.5x time = x-25 = 5 walker I had tried x*x+25= 5 but I then tried to combine the two & got 2.5x^2-12.5x-10=0 I know the answer is 4mph for the jogger & 6 for the walker. Any help on how to get the equation setup or where I'm going wrong would be appreciated.
