Production Rate Comparison: Machine A (30/3min) vs Machine B (16/2min)

Question

In the clothing factory there are two t-shirt machines

Machine A produces 30 t-shirts in 3 minutes,
Machine B produces 16 t-shirts in 2 minutes.

Which machine will produce more t-shirts in 10 minutes?

Step-by-Step Solution

To solve this problem, we'll follow these steps:

  • Step 1: Calculate the production rate per minute for each machine.
  • Step 2: Determine the total production over 10 minutes for each machine.
  • Step 3: Compare the results to determine which machine produces more t-shirts.

Now, let's work through each step:
Step 1: For Machine A, the production rate is calculated as follows:
Production Rate of Machine A = 30 t-shirts3 minutes=10 t-shirts per minute \frac{30 \text{ t-shirts}}{3 \text{ minutes}} = 10 \text{ t-shirts per minute}
For Machine B, the production rate is:
Production Rate of Machine B = 16 t-shirts2 minutes=8 t-shirts per minute \frac{16 \text{ t-shirts}}{2 \text{ minutes}} = 8 \text{ t-shirts per minute}
Step 2: Calculate the total production over 10 minutes for both machines:
Machine A over 10 minutes: 10 t-shirts/minute×10 minutes=100 t-shirts 10 \text{ t-shirts/minute} \times 10 \text{ minutes} = 100 \text{ t-shirts}
Machine B over 10 minutes: 8 t-shirts/minute×10 minutes=80 t-shirts 8 \text{ t-shirts/minute} \times 10 \text{ minutes} = 80 \text{ t-shirts}
Step 3: Compare the production totals:
Machine A produces 100 t-shirts, while Machine B produces 80 t-shirts in the same time period.
Therefore, Machine A will produce more t-shirts in 10 minutes.

Answer

Machine B
