Comment on Wind Chill Factor - Question II
I am sorry this question
That's understandable.
That's understandable. However, when it comes to temperature, the higher/more/greater/bigger the number, the hotter the temperature.
can you please explain , if
If the temperature is AT MOST
If the temperature is AT MOST -5 degrees, then the temperature must be LESS THAN OR EQUAL TO -5 degrees.
So for example the temperature COULD be -10 or -5, or -22 or -31 or....
Does that help?
Cheers,
Brent
I have a question regarding
Great question.
Great question.
We're examining ranges, because the question tells us that "the temperature is AT MOST -5 degrees Fahrenheit"
In other words, we're told that the temperature could be anywhere in the range of temperatures from -5 all the way down to super low low low temperatures. This is why I highlighted those various temperature in yellow.
Also, when we examine the scenario when the wind is 5mph, we're looking for an air temperature that would result in a perceived temperature of -29 degrees.
Unfortunately, there is no air temperature (when combined with a wind speed of 5 mph) that yields a perceived temperature of exactly -29 degrees.
We know that an air temperature of -15 degrees yields a perceived temperature of -28 degrees, and we know that an air temperature of -20 degrees yields a perceived temperature of -34 degrees.
Since -29 degrees is between -28 degrees and -34 degrees, this means the air temperature must be between -15 and -20
Does that help?
Cheers,
Brent
Hey, it is a very nice
Looking at the real-world scenario, it is likely that there will be ranges and at some point, it will be -29 degrees, but in the test, how can I know that it is viewed as ranges? Can it be a question like that in the test where it did not mention that it uses ranges?
Great question.
Great question.
The problem is, we could never create a chart that includes every possible temperature (e.g., -13.42125 degrees) and every possible speed (e.g., 27.76 mph.), so, unless you're given values that match those in the table, you're going to have to use ranges.
Similarly, we might create a table that converts Celsius to Fahrenheit.
The table might look something like this:
C | F
-20 | -4
-10 | 14
0 | 32
10 | 50
20 | 68
For this table, a legitimate GRE question might ask you to find the Celsius equivalent to 21 degrees Fahrenheit, and the answer would be given as ranges.
