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?

Verified Answer :

|x – 55| = 4.2

where x is the speed.

-4.2 < x - 55 < 4.2

-4.5 + 55 < x < 55 -4.2

50.8 < x < 59.2

The upper boundary for x is 59.2 

The speed must be in the range  55 - 4.2 to 55 + 4.2.
