So first off, let's define what a median is: in the list of answers (listed from least to greatest) the number i the middle is the median.
Just like I said, line up the numbers in order of smallest to largest: 12, 14, 14, 14, 15, 16, 16, 18, 18, 19, 21, 22
Now find the number in the middle. It should be 16.
*Just a note for the future: when there's an odd number of integers, the median will just be that number in the middle. Example: 1,4,5; 4 is the median. Now, if there are an even number of integers, the median will be the average between the two middle numbers. Example: 1,4,5,7; the two numbers in the middle are 4 and 5. Take the average between the two (4+5)/2 and you would get 4.5*
The distance (d) traveled by the airplane is the product of multiplying the speed (s) and the trip took (h). The equation is shown below, d = s x h Substitute the known values to the equation, 637.5 miles = (150 mile/ hour) x h Manipulating the equation, h = (637.5 miles) / (150 mile/ hr) h is equal to 4.25 hours.
Now when we talk about place values we have ones tens hundreds thousands ten thousands and so on. So when you look at no.1 its place value is ones because 1 is the first value.
So 2 is in tens.
Now the difference of tens and hundreds is tens follows the 2 place value and hundreds the next.
