The first thing you bought was a flight ticket, not shirt or shoes.
''I flew to Japan I bought shoes and I bought a shirt what did I buy first?'' passes for a simple mathematical puzzle and certainly requires the use a form of deductive reasoning and inference to be answered correctly.
<h2>Further Explanation</h2>
There are three things in the sentence that is worthy of note: Firstly, the buying of shoes, secondly, the purchase of shirt and thirdly, ''flew to Japan''.
A careful consideration must be based on what you bought that enabled you to get to the Japanese country. It is a known fact that if one must fly to another country, then a flight ticket must be purchased. To arrive at the correct answer, the only thing that enables you to get to the country to buy shoes and shirt was a flight ticket you got at the airport.
If the flight ticket was not purchased, even with your money with you, to buy the type of shoes and shirt you wanted to buy from Japan, you would not have been able to buy those items.
Therefore, if you flew to Japan to buy shoes and a shirt, you will have bought a ticket first.

<span>Find the wind speed and the plane's airspeed.
:
Let s = speed of the plane in still air
Let w = speed of the wind
then
(s-w) = plane speed against the wind
and
(s+w) = plane speed with the wind
:
Change 3 3/8 hrs to 3.375 hrs
:
The trips there and back are equal distance, (1890 mi) write two distance equations
dist = time * speed
:
3.375(s-w) = 1890
3.0(s + w) = 1890
:
It is convenient that we can simplify both these equations:
divide the 1st by 3.375
divide the 2nd by 3
resulting in two simple equations that can be used for elimination of w
s - w = 560
s + w = 630
----------------adding eliminates w, find s
2s = 1190
s =
s = 595 mph is the plane speed in still air
Find w
595 + w = 630
w = 630 - 595
w = 35 mph is the wind spee</span>
1 Millimeter is the answer I hope this helps you.
We call two numbers a and b, notice a>b
<span>The sum of two numbers is 110: a+b=110
</span><span>The larger number is 2 less than 7 times the smaller: a=7b-2
And by replacing a=7b-2 we have an equation: 7b-2+b=110
or 8b=110+2, and 8b=112, that means b=112:8= 14
We have two numbers: 14 and 96</span>
