Answer:
12 trips will be needed to carry 14 cords of the wood.
Step-by-step explanation:
We will use unitary method to solve this problem.
∵ Pick up truck carry [tex]\frac{7}{6}[/tex] cord of firewood in trip = 1
∴ Pick up truck will carry 1 cord of firewood in the trips = [tex]\frac{1}{\frac{7}{6}}[/tex] tips
= [tex]\frac{6}{7}[/tex] trips
∴ Truck will carry 14 cords of firewood in the trips = [tex]\frac{14\times 6}{7}[/tex]
= 12 trips.
Therefore, 12 trips will be needed to carry 14 cords of the wood.
