Distance traveled while attention is elsewhere

A fictional classroom exercise gives a vehicle a constant speed of 55 miles per hour. The driver looks away from the road for four seconds. The worksheet defines one mile as 5280 feet and one hour as 3600 seconds, and asks for the distance covered during the glance. It deliberately excludes braking and does not claim that the driver immediately recognizes or responds to a hazard afterward. A learner interprets the result as a stopping distance and another treats a hands-free conversation as proof that attention cannot be diverted. The instructor asks for the conversion and the limits of the conclusion. The task supplies no actual road, visibility, vehicle braking performance or permission to use a phone. A correct answer separates distance traveled without observation from a complete hazard-response model.
