Final answer:
The correct answer to how far ahead a motorist should look on city roads is 5 seconds. This amount of time allows for safe reaction to potential road hazards.
Step-by-step explanation:
When driving on city roads, a motorist should look ahead a certain number of seconds to ensure they have ample time to react to any potential hazards. The correct answer is (c) 5 seconds. This allows for adequate time to notice and respond to other vehicles, pedestrians, or any unexpected events.
Bridget's observation about cars traveling 50 m in 3 s relates to understanding vehicle speeds and distances, which is an important aspect of road safety.
When driving on city roads, a motorist should look at least 2 seconds ahead.
This allows the motorist to have enough time to react to any potential hazards or changes in the road ahead.
For example, if a motorist is driving at a speed of 40 mph, looking at least 2 seconds ahead would mean scanning the road for about 117 feet in front of the vehicle.
