Question 1001307: Patton walked part of the 76 miles to the site of the battle and rode the rest of the way on a caisson. He walked at 4 mph and rode at 15 mph. If the total time of the trip was 8 hours,for how long did he walk?

We have rate times time = distance.
Let x be the amount of time he walked.
Thus 8-x is the time he rode.
Then we can write
4x+15(8-x)=76
4x + 120 - 15x = 76
-11x = -44
x = 4 hours
