Increasing a car's speed from 0 mph to 30 mph requires a great deal of work as the car has to overcome inertia and gain momentum from a stationary position. On the other hand, increasing the speed from 50 mph to 60 mph does not require as much work as the car is already in motion and only needs to accelerate by an additional 10 mph. Therefore, option B which is increasing from 50 mph to 60 mph requires less work.
