Final Answer:
The stopping distance on dry surfaces for passenger car is 247 ft.
Therefore, correct option is 2) 247 ft.
Step-by-step explanation:
At a speed of 50 mph, the stopping distance on dry surfaces for a passenger car is approximately 247 ft.
Stopping distance is influenced by factors like speed, reaction time, and road conditions. At 50 mph, it takes a certain distance for a vehicle to come to a complete stop, considering the time it takes for the driver to react and the braking distance.
The stopping distance can be calculated by adding the perception distance (the distance traveled during the driver's reaction time) to the braking distance (the distance the car travels while coming to a complete stop). At higher speeds, the braking distance increases significantly, making it essential for drivers to maintain a safe following distance and be attentive to the road conditions.
Therefore, correct option is 2) 247 ft.
