Of course we all know that going from Illinois to New York does not take one minute. The man on the phone should have waited while the airport was looking for his information.Instead of hanging up on "Just a minute.."
On 2 Broke Girls Caroline (Beth Behrs) gave her female enemy a math problem. It went something like this: If a train starts at 9 AM and travels 800 miles and ends at 5 PM how fast was the train going? The answer of course is 100 miles per hour.
D=RT
D=distance in miles
R=miles per hour
T=time in hours
So lets plug the numbers in knowing that 9 AM to 5 PM equals 8 hours.
D=RT
800=R x 8
We divide both sides of the equation by 8 will get 100 miles per hour which is the correct answer: 100=R
Now let's do the distance between Illinois to New York which is 808 miles and suppose time is just one minute or 1/60 of an hour.
D=RT
808=R x (1/60)
let's invert the fraction (1/60) into (60/1) and multiply that by both sides of the equation:
(60/1) x 808=R x (1/60) x (60/1)
(60/1) x 808= R x 1
(60/1) x 808=R
,
48,480 = R
And there we have it, if a plane can travel 808 miles in one minute then the plane must be going 48,480 miles per hour.It won't matter if you have a window seat or not everything will be a blur :)
Now while I was in navy boot camp we had taps (bedtime) at
9:30 PM and we were awaken at 4:30 AM how many hours is that?Figured it in your head.
Well, let's first add 12 to the AM hour changing 4:30 into 16:30 and subtract the PM hour from that or
16:30 - 9:30= 7 hours.
But how about adding 12 to the PM hour instead? Well, you can but then you have to subtract that result from 24.
9:30 PM change that into 21:30
21:30 - 4:30 =17
24-17=7
As you can see this method takes one more step.
Now something like 9:45 PM to 4:15 AM is harder to figure in your head better off using pencil and paper or counting with your fingers.
