Orlando bought a plot of land measuring 1 square mile, on which he plans to grow blueberries. He hires 346 people to plant seedlings. It takes about 20 seconds to plant each seedling, and each seedling requires 1.5 square feet of area.

a. How many square feet of land can teh 346 workers plant each minute? Explain your strategy using words/numbers.
b. How much time will it take to plant the entire plot of land? Explain your reasoning and strategy using words and/or numbers.
c. Orlando decides to plant a different type of blueberry that requires only 1.2 square feet of land per seedling. How much time will it take the workers to plant these seedlings? Explain your strategy using words/numbers.

Jesse's Problem

There are 7 girls on a bus. Each girl has 7 backpacks. In each backpack there are 7 big cats. Each big cat has 7 small cats. How many legs are on the bus? The bus driver does not count. The backpacks are on the bus and do not have legs. Wheels on the bus do not count!

YOU MUST EXPLAIN IN WORDS YOUR THINKING AND CALCULATIONS!!!

Good luck :-)
