Answer

It took him 40 minutes to plant each tree.

Solution

We first convert 7 1/3 hours into an improper fraction. Since   7 1/3 = (7 × 3 + 1)/3 = (21 + 1)/3 = 22/3 hours, and assuming David planted 11 trees today, the time spent on each tree is   (22/3 hours) ÷ 11 = 22/(3 × 11) = 22/33 = 2/3 hour. To convert 2/3 of an hour into minutes, note that 1 hour = 60 minutes, so   (2/3) × 60 = 40 minutes. Thus, it took him 40 minutes to plant each tree.

To find out how long it took David to plant each tree, we first convert \( 7 \frac{1}{3} \) hours into an improper fraction. This can be done by transforming it into \( \frac{22}{3} \) hours. Then, we divide this time by the number of trees, which is 11. So, \( \frac{22/3}{11} = \frac{22}{3} \times \frac{1}{11} = \frac{22}{33} = \frac{2}{3} \). Thus, it took David \( \frac{2}{3} \) hour to plant each tree. He planted each tree in \( \frac{2}{3} \) hours, which is equivalent to 40 minutes. So the next time someone asks how long a task took, remember that breaking it into smaller parts often reveals interesting insights. Time management can become a tree of possibilities!
