A car is traveling at a rate of 50 miles per hour, while a motorcycle is traveling at 70 miles per hour. The car takes 4 hours longer to arrive at the destination. The equation representing the scenario is 50(x + 4) = 70x. What can be concluded about the equation? Check all that apply.
a. The scenario is translated to car's travel distance = motorcycle's travel distance.
b. The expression 70x represents the hours the motorcycle traveled.
c. The expression (x+4) represents the number of hours traveled by the car.
d. The variable x represents the total hours driven by the motorcycle.
e. The car's travel distance is represented as 50(x+4).
