Final answer:
During a microsleep of 4-5 seconds, a vehicle traveling at 50 mph could travel nearly the length of a football field, making option 1 the correct choice.
Step-by-step explanation:
During a 4-5 second microsleep, a vehicle traveling at 50 mph can cover a significant distance. Since 50 mph is approximately 22.35 meters per second, over a period of 4 seconds, the vehicle would travel about 89.4 meters, and over 5 seconds, about 111.75 meters. A standard American football field is 120 yards (approximately 109.7 meters) from end zone to end zone, therefore, within 4-5 seconds, the vehicle could travel the length of almost an entire football field. This makes option 1 the correct choice.
