Give the step-by-step reasoning process and then the final answer. Heath spent his weekend helping at his uncle’s farm planting carrots. He planted 400 rows of carrots with 300 plants in each row. He used a machine to get the planting done and it took him 20 hours. How many carrots did he plant each hour?
Heath planted 400 rows x 300 plants = 120,000 carrot plants. He planted 120,000 plants in 20 hours, or 120,000 / 20 = 6,000 plants per hour.
The final answer: 6000.
