What is the mean mass of the vehicle including the mass (75 kg) of the average driver?

• A. 1369.793 kg
• B. 1200 kg
• C. 1500 kg
• D. 1700 kg

Answer: (A)

Think of the total mass as the sum of two parts: the vehicle’s own mass and the mass of the driver. To include the driver, you add 75 kg to the car’s mass. If the vehicle’s mass is 1294.793 kg, then the total mass with the average driver is 1294.793 + 75 = 1369.793 kg. That matches the given total. This approach is why the answer works: you’re counting everything that contributes to the weight of the vehicle when it’s being used with an average driver.
