Answer:
1 hour 12 minutes.
Step-by-step explanation:
Let the number of hours = t
Ted can clear the field = [tex]\frac{t}{3}[/tex]
Jacob can clear the field = [tex]\frac{t}{2}[/tex]
Together they can clear the field = [tex]\frac{t}{3}[/tex] + [tex]\frac{t}{2}[/tex] = 1
[tex]\frac{3t+2t}{6}[/tex] = [tex]\frac{6}{6}[/tex]
2t + 3t = 6
5t = 6
t = [tex]\frac{6}{5}[/tex]
t = 1.2 hours.
converting 1.2 hours = 1 hour 12 minutes.
It would take 1 hour 12 minutes to clear the field together.
