Final answer:

A vehicle traveling at 55 mph covers approximately 161 feet in 2 seconds, which is the duration of glare blindness stated in the question. None of the provided options are correct for this scenario.

Step-by-step explanation:

To calculate the distance a vehicle travels during a period of glare blindness, you need to use the formula for distance, which is distance = speed x time. We have the speed in miles per hour (mph), which we need to convert to feet per second (fps) to get the distance in feet. Since 1 mile equals 5280 feet, a vehicle traveling at 55 mph is moving at 55 x 5280 feet per hour. There are 3600 seconds in an hour, so to convert to fps, we divide by 3600.

The calculation is as follows:

  • Convert mph to fps: 55 mph * 5280 ft/mile / 3600 sec/hour = 80.67 fps
  • Calculate the distance traveled in 2 seconds: 80.67 fps * 2 sec = 161.33 ft

The vehicle will travel approximately 161 feet in 2 seconds of glare blindness at 55 mph, which means the correct answer is not listed in the provided options. Therefore, you would need to communicate this discrepancy to the student.
