5003 Praxis Practice Test Practice Question
A car travels at a constant speed of x miles per hour. Which of the following expressions gives the distance in miles, the car will travel in hours?
Correct Answer: C
Rationale: To determine the distance traveled by a car moving at a constant speed, the formula used is distance = speed × time. Here, the speed is represented by x (miles per hour) and time by t (hours). Thus, the expression for distance is xt.
Option A (x+t) incorrectly adds speed and time, which does not represent distance. Option B (t+x) suffers from the same flaw, simply rearranging the terms without addressing the multiplication needed for distance. Option D ((xt)²) suggests squaring the product, which misrepresents the relationship between speed, time, and distance. Therefore, xt accurately captures the required calculation.
