A Chapter Takes 65 Minutes To Read. Express 65 Minutes As An Improper Fraction Of An Our In

If you're traveling 60 miles an hour, how long does it take to travel 1 mile?

We called this "factor labeling" in school.[math]\frac{60\quad miles}{hr} \times \frac{1\quad hr}{60\quad minutes} [/math] You start with  you original fact: 60 miles / hr and write it in full fraction form as above. Then you use your conversion fractions, and write them so the units cancel. In this case, we know there are 60 minutes in 1 hour, ie, 60 minutes / 1 hr, so that conversion can be written[math]\frac{60\quad minutes}{1\quad hr} or \frac{1\quad hr}{60\quad minutes}[/math] So in your case, we use [math]\frac{1\quad hr}{60\quad minutes} [/math] so the units, ie, "hours" cancel off, leaving you with whatever units remain, ie, "miles per minute". Divide and multiply all the magnitudes leaving you with a final answer. 60 / 60 = 1, thus, [math]\frac{1\quad mile}{minute}[/math]

Is reading a book summary better than reading the whole book? What is your experience?

"I've read entire books only to realize that less than a third of the book was actually useful to what I needed to know".Given that your aim is to know, that is, you read books solely for information, then in certain cases it definitely makes a lot of sense. A lot of books have a core idea, which can be easily summarised, and the rest is just evidence and fleshing out and justifications. For instance, I recently read Guns, Germs and Steel, a book whose premise is that geography and environment play a huge role in the nature and strength of cultures, and which cultures prevail and which ones are wiped out over time. After that, it was just pages and pages of historical evidence and data to support the claim. I could have easily read a few page summary of the book.BUT. We don't always read for information, do we? The entire fiction and poetry book industry sure hinges on that fact. And it is true, at least in my experience. Of the books I read, barely a quarter are non-fiction. And in these cases, it make zero sense to read a summary of the book.'It's like travelling, I guess. When you are travelling to get somewhere, of course you want to get there fast, use a car for example. But sometimes you are out only to experience, to enjoy, to stroll leisurely through the wonders of the road. And then it wouldn't make sense to rush through, would it?So there's your answer. If you are reading for information, and if the book can be condensed without losing its essence, then maybe one can make do with the summary. But not if you are in it for the story.Imagine reading the Harry Potter books, savoring all the little moments and twists and turns, and compare that with someone telling you the plot in ten minutes. Hardly the same thing, let alone better!One exception could be a book that draws you in, but then turn out not be quite good enough to keep reading it, like a sudden rain on your peaceful stroll. Then, it might make sense to some, but even then I do my best to not do it.

When will this earth come to its end?

The sun is getting hotter before it turns into a red giant. In fact the sun will be 67% more intense long before the sun starts to swell.In about 800 million years the suns solar output will increase by 10% as it moves down the standard sequence timeline, this is normal and expected. Starting as that increase becomes significant, all forms of animal and plant life will start to die and around 1 billion years from now only microbes will be left from the heat of our dying sun. The earth is actually starting its golden years, its not a juvenile or even an adult … it's a full fledged AARP member looking towards the sunset of its life.Shortly after that in cosmic time, if the sun doesn’t swell enough to swallow the earth. The earth is likely to drift off on its own as our dying sun sheds its bloated mass close to its end. The earth, cold, dark, lifeless, floating alone … the echo of everything we once were. Drifting endlessly and going nowhere for trillions upon trillions of years. The essence of every experience the substance of everything you ever touched or that touched you will be there with it. The glory that was our earth and all the life in it, everyone you ever knew will still be there. Ashes to ashes, dust to dust, our world a lost soul forever in a sea of darkness.What may save the Earth from being swallowed by the sun in the end. The Earth is slowly moving away from the sun at 15 cm per year due to tidal force bleeding angular momentum from the sun and transferring it to the earth by moving it farther away. This and the expansion of space at 75 km per second per megaparsec will move Earth's orbit 40–50 million miles farther from the Sun by the time the Sun turns into a red giant. The planets orbits are actually chaotic over billions of years. It is impossible to predict other than the solar system wont look the same in 5 billion years.
