Question

what should you do to maintain a constant speed when driving uphill?

gently apply the brake

increase pressure on the accelerator pedal

decrease pressure on the accelerator pedal

maintain a firm hold on the steering wheel

Explanation:

Analyze the effect of gravity on an incline

When driving uphill, the component of gravity acting parallel to the slope opposes the forward motion of the vehicle, naturally slowing it down.

Determine the required driver action

To counteract this opposing gravitational force and maintain a constant speed, the engine must produce more power, which requires the driver to increase pressure on the accelerator pedal.

Evaluate the given options

• "gently apply the brake": This would slow the vehicle down further.
• "increase pressure on the accelerator pedal": This provides the necessary engine power to overcome gravity and maintain speed.
• "decrease pressure on the accelerator pedal": This would cause the vehicle to lose speed rapidly.
• "maintain a firm hold on the steering wheel": While good for control, this does not directly regulate speed.

Answer:

• gently apply the brake
• increase pressure on the accelerator pedal (Correct answer)
• decrease pressure on the accelerator pedal
• maintain a firm hold on the steering wheel
