2. A crew plants 1200 pine trees every 3 days on average. How many pine trees can that crew plant...

If the crew plants 1200 pine trees every 3 days, they plant 1200/3 = 400 pine trees per day. Therefore, in 12 days, they can plant 400 * 12 = 4800 pine trees.

It takes the crew 3 days to plant 1200 pine trees, so they can plant 1200/3 = 400 pine trees per day. In 12 days, they can plant 400 * 12 = 4800 pine trees.

The crew plants 1200 pine trees every 3 days, so in 1 day they can plant 1200/3 = 400 pine trees. Therefore, in 12 days, the crew can plant 400 * 12 = 4800 pine trees.
