So i was the town hall the video clip where the woman couldn't prize the question; then i thought: what if she *did*, but in means that rotate the tables, leaving the questioner flabbergasted. Right here I am, at work, thinking about the many convoluted method to resolve this problem. Here's what I came up with:

Let x be the moment in hours it take away to go 80 miles. Set v(t) = 80.

You are watching: Going 80 mph for 80 miles answer

∫v(t)dt = 80 from 0 come x

Then 80x - 80(0) = 80

80x = 80

x = 1 hour

How would certainly you answer this question, if you wanted to mess v that person?

How long does it require to go 80 miles if you're walking 80mph? The prize is simple.

80 mile is the about half the broad of Florida. Florida is wherein Disney people is. Disney world is where Mickey mouse lives. Mickey computer mouse is in countless movies. Movies are made in Hollywood, California. California is wherein the gold sirloin happened. Often, yellow rushers would find a solitary gold nugget. Obviously yellow is an excellent because it has actually a monetary value. We also know that time is money. Just how much money is one gold nugget worth? One hour. And also there is your answer.

If i am going 80 miles every hour, it would certainly take me 10 minute to go 80 miles.

Since ns am not going 80 miles every hour, the statement is vacuously true.

You could expand your answer through re-deriving the entire integral calculus.

You can expand the by structure up the interpretations of genuine numbers indigenous ZFC. *Then* usage those to re-derrive integral calculus.

We know that there room 60 minutes in an hour. If we're traveling at a rate of 80 mph, then that means we're traveling at 80/60 = 8/6 = 4/3 miles every minute. ~ one minute we travel 4/3 miles. After two minutes we travel 4/3 + 4/3 miles. ~ 3 minutes we travel 4/3 + 4/3 + 4/3 miles. For this reason after one hour (sixty minutes) we travel Σ(4/3)i whereby i goes indigenous 1 to 60. Therefore after one hour, we take trip 4/3 * 60 = 240/3 = 80 miles.

To further convolute your answer, justify why it's a consistent speed. You feeling no force, because of this F = 0. You have actually mass, therefore by Newton's second law a = 0. Because a = 0, v = constant.

Thus after one hour (sixty minutes) we travel Σ(4/3)i wherein i goes from 1 to 60.

Careful. Don't include the index in the summand in this case.

How about I shot to add technicalities to make her right.

My physics teacher drilled right into our heads the velocities room all relative.

Assumptions made: She answered 10 minutes. A airplane overhead travels at 480 miles per hour.

Maybe she ignored 80 mi/hr since they wherein not moving. They room a resolved reference allude to something else. She reply let's to speak 10 minutes because her reference point was a aircraft overhead. The airplane being the only thing, maybe, in her see that to be moving. If the plane was the reference suggest to them, castle were moving about, let's say, 480 mph away from it. Again that was v the airplane as the reference point. Of course the velocity 480mph would be negative because she is relocating away indigenous it as she is idle. Together a result, she normalized the velocity to give her the speed. The speed, currently normalized, is simply positive 480 mph. At the speed, girlfriend hit 80 miles in 10 minutes.

In all, instances, she to be right. The girl questioning her never ever specified a suggest of reference. She just implied one.
