Answer: 1000

Explanation:

If one person can pick up a plate every 10 seconds, then the rate of picking up plates can be represented as 1 plate/10 seconds.

When two people are picking up plates, the rate doubles, so it becomes 2 plates/10 seconds or 1 plate/5 seconds.

To find how long it will take for 200 people to pick up plates, we need to use the formula:

time = amount ÷ rate

  • where an amount is the number of plates needed (in this case, 200), and the rate is the rate at which plates are being picked up (1 plate/5 seconds).

Plugging in the values, we get:

time = 200 plates ÷ (1 plate/5 seconds)

time = 200 plates × 5 seconds/plate

time = 1000 seconds

Therefore, it will take 1000 seconds for 200 people to pick up plates at a faster rate.

I hope that this answer has helped you!

Time = Time per person * Number of people

Time = 10 seconds * 200 people

Time = 2000 seconds

Therefore, it will take 2000 seconds for 200 people to pick up plates from the faster buffet line.
