Your steering input is ___ of a second faster than the amount of time it takes you to brake.
Ronch [10]

The correct answer is; 1/4.

Further Explanation:

When a person is starting to use their brakes in a vehicle the steering is approximately 1/4 a second faster. This means that the steering wheel input can be used before the brakes in an emergency. If you need to steer a different direction to not hit someone the steering will work before the brakes.

All modern cars now have power steering and the steering is more easy than it was in older cars. The fluids in cars should be checked monthly especially the power steering fluid. This helps to keep the vehicle in great running condition.
