siniylev [52]
By connecting the distances traveled by the jet and the distance between them, we form a right triangle with hypotenuse equal to the unknown distance.

                             h² = a² + b²
Substituting,
                             h² = (108 mi)² + (214 mi)²
                               h = 239.71 miles
Thus, the distance between them is approximately 239.71 miles.

<em>We already have our first value 75 and the second value 24. Let's assume the unknown value is Y which answer we will find out.</em>

<em>We already have our first value 75 and the second value 24. Let's assume the unknown value is Y which answer we will find out.As we have all the required values we need, Now we can put them in a simple mathematical formula as below:</em>

<em>7</em><em>5</em><em> </em><em> </em><em>× 100</em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em>1</em><em>0</em><em>0</em>

<em><u>STEP 3</u>>> Y = 32</em><em>%</em>

<em>Finally, we have found the value of Y which is 32 and that is our answer.</em>
