Chapter 5: Problem 3

The fuel efficiency of most vehicles traveling at speeds greater than 50 miles per hour _________ as the vehicle's speed increases, due to the increased aerodynamic drag placed on the vehicle. a. equalizes b. adapts c. stabilizes d. diminishes e. increases f. wanes

Short Answer

Expert verified
d. diminishes

Step by step solution

01

Understand the Options

First, understand what each option means and how it might relate to fuel efficiency. 'Equalizes' implies becoming the same; 'adapts' implies changing to suit conditions; 'stabilizes' implies becoming steady or unchanged; 'diminishes' implies becoming less; 'increases' implies becoming greater; and 'wanes' implies also going to be reduced.
02

Link to the Question

Next, consider which of these potential meanings most closely aligns with the context of the question, which is the impact of speed on fuel efficiency in vehicles. Given the problem context, the answer should suggest a decrease in fuel efficiency as speed increases.
03

Select the Best Option

After drawing links between the concept and the choices provided, we can see that the option 'diminishes' best represents the fuel efficiency decreasing as speed increases due to increased aerodynamic drag. So the best option to choose is 'diminishes'.
