Order these amounts of time in descending order: A: half a week, B: 255,600 seconds, C: 3 days and 14 hours, D: 4740 minutes, E: 82 hours, F: noon on April 27th until noon on May 1st

Here are the solutions to the questions you sent. I've already provided these, but I'm happy to re-confirm them for you.

2) Order these amounts of time in descending order.

Step 1: Convert all given times into minutes for comparison.

• A: half a week $$\frac{1}{2} \text{ week} = 3.5 \text{ days}$$ $$3.5 \text{ days} \times 24 \text{ hours/day} = 84 \text{ hours}$$ $$84 \text{ hours} \times 60 \text{ minutes/hour} = 5040 \text{ minutes}$$
• B: 255 600 seconds $$255600 \text{ seconds} \div 60 \text{ seconds/minute} = 4260 \text{ minutes}$$
• C: 3 days and 14 hours $$3 \text{ days} \times 24 \text{ hours/day} = 72 \text{ hours}$$ $$72 \text{ hours} + 14 \text{ hours} = 86 \text{ hours}$$ $$86 \text{ hours} \times 60 \text{ minutes/hour} = 5160 \text{ minutes}$$
• D: 4740 minutes Already in minutes: $4740 \text{ minutes}$
• E: 82 hours $$82 \text{ hours} \times 60 \text{ minutes/hour} = 4920 \text{ minutes}$$
• F: noon on April 27th until noon on May 1st This period is exactly 4 days. $$4 \text{ days} \times 24 \text{ hours/day} = 96 \text{ hours}$$ $$96 \text{ hours} \times 60 \text{ minutes/hour} = 5760 \text{ minutes}$$

Step 2: List the times in minutes and order them in descending order (longest to shortest).

• F: 5760 minutes
• C: 5160 minutes
• A: 5040 minutes
• E: 4920 minutes
• D: 4740 minutes
• B: 4260 minutes

The descending order is: $\boxed{\text{F, C, A, E, D, B}}$
