The pirates plan to explore 4 islands. Two islands require walking 20 miles per day while the other two islands require 25 miles per day. How many miles will they have to walk if it takes 1.5 days to explore each island? Think carefully first, then make a decision:

Sure, I'd be happy to help.

If you explore one island in 1.5 days, that means you're walking for 1.5 days × 24 hours = 36 hours = 8.25 days, which is not a whole number of days. So, the duration should be in terms of days, not hours.

Now, let's break down each island's walking requirement duration-wise. For the two islands that require 20 miles per day, in a day, the pirates walk 20 miles. In 1.5 days, they would walk 20 miles per day for 1 day + for ½ day, they'd walk 20 miles/2 = 10 miles. So, in the first island, they would walk 20 + 10 = 30 miles. Similarly, in the second island, they'd walk 20 + 10 = 30 miles.

For the other two islands, in one day, the pirates walk 25 miles, and in 1.5 days, they walk 25 miles/day for 1 day + for ½ day, they walk 25 miles/2 = 12.5 miles. So, in the third island, they would walk 25 + 12.5 = 37.5 miles. And, in the fourth island, they would walk 25 + 12.5 = 37.5 miles.

So, overall, the pirates would walk 30 miles + 37.5 miles + 37.5 miles + 37.5 miles. Reducing, we get 140 miles.

Therefore, the pirates would have to walk 140 miles.

I hope that helps! Let me know if you have any other questions.

Here's how to approach this problem:

1. First, calculate the total miles needed to explore each island. Since it takes 1.5 days to explore each island, the pirates will have to walk:
   - For the 20-mile islands: 20 miles/day * 1.5 days = 30 miles
   - For the 25-mile islands: 25 miles/day * 1.5 days = 37.5 miles

2. Then add up the miles for all islands:
   - Two 20-mile islands: 2 * 30 miles = 60 miles
   - Two 25-mile islands: 2 * 37.5 miles = 75 miles

3. The pirates will have to walk a total of 60 miles + 75 miles = 135 miles to explore all four islands.

So the answer is that they will have to walk 135 miles.
