When driving, you should attempt to scan 20-30 seconds ahead of your vehicle. If you are traveling at highway speeds (50, 60, 70 miles per hour), you will travel about one mile per minute. Therefore, you should be scanning about how far ahead?

A. About 100 feet
B. About 500 feet
C. About 1/2 mile
D. About 1 mile

Answer :

Final answer:

When driving at highway speeds (approximately one mile per minute), scanning 20-30 seconds ahead means scanning roughly 1/2 to 1/3 of a mile in front of your vehicle. This corresponds to Response C in the multiple-choice question.

Explanation:

The subject pertains to the understanding of motion, velocity, and distance, making it a physics-related question. When you're driving at highway speeds like 50, 60, 70 miles per hour, you're covering approximately one mile per minute. If you scan 20-30 seconds ahead, you're effectively scanning 1/2 to 1/3 of a mile ahead, because 20-30 seconds is 1/2 to 1/3 of a minute. Therefore, the accurate answer is c. About 1/2 mile.

To further explain the concept, let's consider some examples. Suppose you're driving at 60 miles per hour and need to scan 20-30 seconds ahead. In terms of distance, you'd realize that if you're moving at 60 mph, you travel one mile in one minute (60 seconds). Consequently, for 20-30 seconds, you'd cover about 1/3 to 1/2 mile down the road.

This concept is similar to understanding the idea of instantaneous speed (the speed at a specific moment in time, as indicated by a car's speedometer) compared to average speed (total distance traveled over total time).
