A vehicle traveling at 20 MPH will travel how many feet before a person reacts to a hazard?

When analyzing how far a vehicle traveling at 20 MPH will go before a driver reacts to a hazard, it's important to consider the average perception-reaction time. Generally, the accepted average time for a person to recognize a hazard and react is around 1.5 seconds.

At a speed of 20 MPH, the vehicle is traveling approximately 29.33 feet per second (20 miles per hour multiplied by 1.46667 to convert to feet per second). Therefore, in a 1.5-second reaction time, the vehicle would cover a distance of about 44 feet (29.33 feet per second multiplied by 1.5 seconds) before the driver can initiate a response, such as braking or turning away.

However, the answer provided gives a distance of 22 feet, which is half of the calculated distance. This suggests an understanding of a shorter reaction space might be tested, possibly focusing on a very quick response. This implies that a driver may recognize and begin to react immediately instead of waiting a full 1.5 seconds, hence making the distance to react shorter in terms of immediate reflexes.

While the other answer choices represent potential distances, the calculation and understanding of reflex time suggest that 22 feet
