✈️ Imagine this: An airline just bought two brand-new airplanes. One of them can zoom through the skies at 600 miles per hour 🌬️, while the other one is even faster, cruising at 720 miles per hour 🚀. Now, here’s the question: In just 12 seconds, how much farther can the faster plane travel compared to the slower one?

🤔 Let’s break it down. First, we need to convert their speeds from miles per hour to miles per second because the question is asking about what happens in just 12 seconds.

🛫 For the slower airplane, traveling at 600 miles per hour, we convert that into miles per second. It turns out that this plane covers one-sixth of a mile every second.

🛬 Now, let’s do the same for the faster airplane, which flies at 720 miles per hour. This one covers one-fifth of a mile every second.

⏱️ So, what happens over 12 seconds? The slower airplane will travel a total of 2 miles. Meanwhile, the faster airplane, with its extra speed, covers 2.4 miles in the same amount of time.

📏 To find out how much farther the faster airplane travels, we subtract the distance covered by the slower airplane from the distance covered by the faster one: 2.4 miles minus 2 miles equals 0.4 miles.

🎯 That’s how much farther the faster airplane travels—0.4 miles. And if we want to express that as a fraction, it’s the same as saying the faster airplane travels two-fifths of a mile farther in those 12 seconds.

So, the answer is two-fifths of a mile.
