5(x + 9)
X + 9
Dr. John left New Orleans at 12 noon. His drummer left at 1:00 traveling 9 mph faster. If the drummer passed Dr. John at 6:00, what was the average speed of each?
What equation does the picture suggest?
The two distances are equal thus:
6x = 5(x + 9)
6x = 5x + 45
X = 45 mph for Dr. John
X + 9 = 54 mph for the drummer
