Answer:
Ryan's maximum time to complete a puzzle is 5 hours
Ryan's minimum time to complete a puzzle is 1 hour
Step-by-step explanation:
<u><em>The complete question is</em></u>
On average, Ryan can finish a puzzle in 3 hours but, depending on the difficulty of the puzzle, his time can vary from the average by 2 hours.
Which absolute value equation can be used to calculate Ryan's maximum and minimum time to complete a puzzle?
Let x represent the maximum and minimum time
we know that
The absolute value of the difference between x and the average must be equal to 2
so
Solve the absolute value
First case (positive case)
Second case (negative case)
Multiply by -1 both sides
therefore
Ryan's maximum time to complete a puzzle is 5 hours
Ryan's minimum time to complete a puzzle is 1 hour
