Given the question "On the freeway, it is unsafe to drive too slowly or too quickly. The safest driving speeds on the freeway near Allan’s town were scientifically determined to be between the minimum and maximum speeds (in miles per hour) according to the equation |x – 55| = 4.2. Which equation can be used to determine the maximum safe driving speed?" To determine the equation that can be used to determine the maximum safe driving speed. Note that |x - 55| = 4.2 means that x - 55 = 4.2 or x - 55 = -4.2 which gives that x = 4.2 + 55 or x = -4.2 + 55 resulting in x = 59.2 or x = 50.8. Therefore, The equation x - 55 = 4.2 is the equation that results in the maximum safe driving speed.
