Question 8 • GA-8th Grade Mathematics
The car and motorcycle travel the same distance to reach the destination, so the equation sets their distances equal. Since the car takes 4 hours longer, if the motorcycle travels for x hours, the car travels for x + 4 hours. Thus x represents the motorcycle’s travel time, and 50(x + 4) represents the car’s distance. The expression 70x is the motorcycle’s distance, not the number of hours traveled.
