<h3>What is Unitary Method?</h3>
Unitary method is a process by which we find the value of a single unit from the value of multiple units and the value of multiple units from the value of a single unit.
Sue spent 1 hour 19 minutes less than Jared
Lucas spent 45 minutes less than Pete.
Pete spent 3 hours reading.
Since, pete spent 3 hours. So, Jared spent
= 3 hours or (180 minutes) - 45 minutes
= 2 hours 15 minutes.
Now, Seu spent = 2 hrs 15 minutes - 1 hour 19 minutes
= 56 minutes

Let Karen works x hours baby sitting
So, she worked (18-x) hours giving music lessons
So,
According to question
5x + 12(18-x)=139
This gives
7*x=77
x=11
So,
<span>Karen worked <em>11 hours baby sitting </em>and (18-11)=7 hours giving music lessons</span>
25x=65
We divide 25 to cancel it out.
65/25=2.6
I would assume 3, because 2.6 is 3 when rounded up.
