Answer 1

"If the time taken by the person to get to work is T minutes, the equality that models this situation is | t - 50 | = 10 the minimum time taken by the person to get to work is 40 min, the maximum time taken is 60 min.

Explanation:

The difference between the time and 50 minutes is 10 minutes.

This can be expressed as:

• |t - 50| = 10

The minimum and maximum time can be found by solving the equation above:

• t - 50 = 10 ⇒ t = 60 minutes,
• t - 50 = - 10 ⇒ t = 40 minutes.

The blanks to be filled in as:

• 1) | t - 50 | = 10,
• 2) 40,
• 3) 60.
