Question

A coal machine can collect 500 pounds of coal an hour. The night shift ran the machine and collected 1,600 pounds of coal. How many pounds of coal will you collect in an 8-hour shift?

Answer 1

A coal machine that collects 500 pounds of coal an hour will collect 4,000 pounds of coal in an 8-hour shift.

Step-by-step explanation:

If a coal machine collects 500 pounds of coal an hour and it collected 1,600 pounds of coal during the night shift, we want to know how much coal it will collect in an 8-hour shift. We can start by calculating how many hours it took to collect 1,600 pounds. Since the machine collects 500 pounds an hour, we divide the total amount of coal it collected by the rate at which it collects:
1,600 pounds ÷ 500 pounds/hour = 3.2 hours.

Now, to find out how much coal will be collected in an 8-hour shift, we multiply the hourly collection rate by 8 hours:
500 pounds/hour × 8 hours = 4,000 pounds.

Therefore, the coal machine will collect 4,000 pounds of coal in an 8-hour shift.
