<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.
Mark spent 1 hour 17 minutes less than Sheila
Sheila spent 55 minutes less than Pete.
Pete spent 3 hours reading.
Since, pete spent 3 hours. So, Sheila spent
= 3 hours or (180 minutes) - 55 minutes
= 2 hours 05 minutes.
Now, Mark spent = 2 hrs 05 minutes - 55 minutes
= 1 hour 10 minutes
